Are you having problems with weevils in your Alfalfa field?
Are you having problems with weevils in your field? If so, this article is for you. Alfalfa weevils are pests that love to eat alfalfa. This can cause major problems if you’re trying to grow healthy crops. Luckily, there’s a way to get rid of these pesky insects and prevent them from destroying your crop.
The best way to avoid infestations is by using insecticide for alfalfa weevils. Insecticides work by killing off any insects that come into contact with them (including disease-carrying ones). These types of products have been shown time and time again to be very effective against all kinds of pests: mites, beetles, and mosquitoes just to name a few examples.
It’s important however before applying any type of product, whether it be organic or conventional, that proper safety precautions be taken because not only do they kill off unwanted invaders but they also kill everything else in their path as well including humans if ingested orally swallowed.
What are Alfalfa Weevils?
Alfalfa weevil is an insect that feeds on the leaves, stems, and seed heads of alfalfa plants. If you have an infestation of alfalfa weevils in your field, it’s important to understand how to identify them and then treat them properly so that you can get rid of these annoying pests as quickly as possible. The alfalfa weevil is a true bug and is the most destructive pest of alfalfa in the northern United States.
Alfalfa weevil adults are tiny, oval-shaped beetles with mottled brownish-yellow bodies and long snouts. The larvae are legless grubs that live underground feeding on plant roots until they pupate into adult beetles.
Alfalfa weevils feed on legumes such as clover and alfalfa if conditions are right for them to do so (warm, dry weather). They lay their eggs at soil level where they hatch into larvae that feed on roots before pupating into adult beetles which emerge from the ground about three weeks later. The life cycle repeats itself once or twice each year unless something interrupts it (like insecticides).
What are the Symptoms of Alfalfa Weevils?
The most common symptoms of alfalfa weevils are:
- A lack of alfalfa in the field.
- Poor quality alfalfa.
- A reduced yield.
- A reduction in the number of stems.
- Damaged stems and leaves indicate that these bugs have attacked your plants and caused significant damage to them throughout the summer.
The symptoms of alfalfa weevils are varied, but they all point to a similar problem: the presence of these pests. For instance, if you’re noticing a lack of alfalfa in your field, that’s a sign that something is eating it. Likewise, if you’re seeing poor quality alfalfa or no yield at all, or even just a reduction in the number of stems, you should consider the possibility that an insect might be responsible.
Damaged stems usually indicate either alfalfa weevil larvae damage or adult feeding (the adults will chew through leaves). Damaged leaves are another sign of adult feeding activity on alfalfa plants; look for holes and tears where leaf edges have been chewed away by hungry adults. Finally, stunted growth can be indicative of larval damage or root-feeding behavior; either way, this symptom doesn’t bode well for your crop.
How Weevils Damage Alfalfa Plant
The alfalfa weevil is a destructive pest that attacks crops, especially alfalfa, beans, and clover. They are tiny, black insects that lay eggs in the soil that hatch into larvae that eat roots and stems. The larvae then pupate and emerge as adults in late summer or fall.
The alfalfa weevil is a common pest of alfalfa and other related crops. These pests burrow into the stems and roots of plants, causing them to wilt and die; The larvae are the most damaging stage that can skeletonize leaves where only leaf veins or holes remain If you want your alfalfa crop to be successful, it is important that you keep these pests away from your field.
The adult weevils feed on leaves, flowers, and pods of the host plants. The female lays eggs singly on stems or leaves near the ground but close to new growth. There are two generations per year (spring and fall) with a partial third generation in most areas of the United States.
Alfalfa Weevils are most active during the spring when temperatures are warmest. You can recognize an infestation by looking for wilted plants with noticeable holes in their stems where the pest has damaged them; this damage will also have discolored or blackened areas around it from where they’ve been feeding on the plant material inside its stem or root structure as well as producing waste products like frass (small pellets) around their entrance holes on top of any discoloration seen on those stem tissue surfaces closest to where those entrances occur within each plant infected by these critters’ burrowing activities before dying off completely due.
How do you get rid of Alfalfa Weevils?
The best alfalfa weevil control method involves knowing how to identify and then use a combination of techniques to control the infestation. This can be accomplished by:
- identifying the problem
- using a combination of methods
- knowing the best time to apply each method
- knowing the best amount to apply
By now you’ve probably heard that pesticides are bad for the environment. They kill off organisms that are not only beneficial to your garden but also essential to keeping pests in check. So there’s a good chance you’re interested in using natural methods instead of killing everything with a toxic chemical cocktail (although if your weevils have mutated into enormous, invincible monsters, go ahead and use pesticides).
The most effective way to control alfalfa weevil populations is by using organic or natural pesticides such as pyrethrin or rotenone. You can apply them directly on the plants where they’ll do the most good, on top of leaves where larvae feed and pupate, or add them to the soil before planting seeds so they get worked in deep enough that larvae can’t burrow below it before they hatch out into adults hungry for leaves.
List of insecticides best for Alfalfa Weevils.
If you’ve found yourself in the unfortunate situation of having to kill Alfalfa Weevils, then I’m sorry. This is not an ideal situation, and it’s one that all of us hope we never have to deal with.
But if you’re here reading this list of insecticides best for killing Alfalfa Weevils, then right now isn’t your time to wallow; it’s time to act. You’ve come here looking for something that will help you get rid of these pests before they do any more damage and prevent them from coming back again next season.
Well, look no further: these are the best pesticides for keeping your alfalfa fields safe from any future infestations by these pests who want nothing more than ruin your crop (and sleep).
#1. Cyhalothrin
Cyhalothrin is a broad-spectrum insecticide that works by attacking the central nervous system of insects. It is a contact and stomach poison, meaning it kills by entering the bloodstream or digestive system. Cyhalothrin is used to control adult alfalfa weevils, fleas, ticks, and other pests in your home and on pets. Cyhalothrin should be applied only in areas where children cannot access it because it is toxic to humans as well as animals if they ingest it or get it on their skin or clothing.
#2. Pyrethrins
Pyrethrins are a class of insecticides derived from the flowers of the chrysanthemum plant. They’re known as synthetic pyrethroids and act as neurotoxins in insect nervous systems. Pyrethrins can be used to control a wide range of pests, including fleas, ticks, and lice; bed bugs, ants, and cockroaches; house flies; mosquitoes; mites, and even mosquito larvae in watery areas like rice paddies.
The active ingredient in pyrethrins is trans-chrysanthemum acid, which is thought to bind to sodium channels (sodium being an important element for nerve function) at certain points along the channel’s outer membrane. When this happens, it causes nerve impulses that would normally pass through unblocked channels instead to fail to reach their destination, resulting in paralysis or death for insects who have been exposed to enough pyrethrin molecules during their attack on your crops.
#3. Vertimec
Vertimec has the active ingredient imidacloprid, which is known to be toxic to a wide variety of pests, including alfalfa weevils. The product is safe for use on most crops and fruit trees, but it can’t be used in organic farming.
Vertimec also has several other benefits: it’s available in pre-measured packages that are easy to apply; each package treats 100 square feet of soil or 25 square feet of plants, and it works for up to one month after application.
#4. Silencer
The silencer is a natural insecticide made from neem oil, and it can be used on a variety of plants. Neem oil has been shown to control many types of insects in the garden, particularly Aphids and White Flies.
The silencer is safe for humans and animals, so you don’t have to worry about being exposed when applying them around your yard or garden. Silencer also smells nice so you won’t mind having it around as much as some other insecticides tend to smell bad.
If you want an environmentally friendly way to control those pesky alfalfa weevils then Silencer might be just what you need. It’s relatively inexpensive compared with other options such as permethrin which costs about $25 per gallon at most stores (and probably more if buying online).
#5. Baythroid
Baythroid is a synthetic pyrethroid insecticide that is used to control several pests, including alfalfa weevils. It has a fast knockdown and kills insects on contact. Baythroid can be applied as a spray or granular treatment to foliage and soil around the base of trees, shrubs, and other plants.
Baythroid is not toxic to humans or animals when used as directed. This product has been shown to be safe for bees when applied at labeled rates during times when pollinators are not active (generally late spring through early fall).
#6. Spinosad
Spinosad is the most effective insecticide for alfalfa weevil control. The weevil has become resistant to many insecticides, including carbaryl, acephate, and chlorpyrifos. Spinosad is safe for use on a variety of crops and it can be applied in a number of ways. It is extremely effective at controlling the alfalfa weevil larvae and adults, as well as other insects that may attack your crops.
Spinosad is a naturally occurring bacterium called Saccharopolyspora spinosa, which produces an insecticidal toxin called spinosyn A. This toxin disrupts the nervous system of insects, causing paralysis and death.
Spinosad works best when it is applied directly to the leaves of the plant; however, you may also spray it on the soil around your plants if you have a large infestation. This will help prevent further damage from occurring while you wait for your plants to grow back from their damaged state.
How Insecticide For Alfalfa Weevils Works
You might be wondering how insecticide for alfalfa weevils actually works. Well, it’s pretty simple: Insecticides are substances that kill or repel pests on contact. An insecticide is a broad-spectrum insecticide if it kills on contact with a wide range of pests including alfalfa weevils and other insects.
Insecticides work by poisoning an insect and causing its death by direct exposure to the poison or through eating something that has been sprayed with it; however, these poisons can also harm humans and other animals if they come into direct contact with them.
When To Apply Insecticide For Alfalfa Weevils
If you want to make sure that your alfalfa weevil control efforts are effective, the best way to do so is by making sure that you apply insecticide for alfalfa weevils at the right time. Monitoring of the Alfalfa weevil should begin in early May and continue through the first harvest and early regrowth.
The best time to apply insecticide for alfalfa weevils is in the early spring or fall when the larvae have been hatched and are eating their way through your plants. This time 1.5-2 larvae per stem are found. This usually happens within a few weeks of when leaves emerge from the ground.
Alfalfa weevil larvae are active from late April through early June. Apply insecticides in early spring before egg laying begins (late March through May). Apply a second application when larvae begin feeding on plants (usually July-August). If necessary, make a third application after harvest when adults begin emerging from pupae.
Apply an insecticide carefully following label instructions until all larvae have hatched out of their eggs into larvae stages, this is when they’re most susceptible to pesticides.
How To Apply Insecticide For Alfalfa Weevils
You can apply insecticide for alfalfa weevils using a backpack sprayer, hand pump sprayer, or tractor-mounted sprayer. If you are seeking an aerial application, you may want to consider the use of an airplane.
Since these chemicals are harmful if ingested by humans or animals, take precautions when handling them: wear eye protection such as goggles or glasses; wear long-sleeved shirtsleeves tucked into gloves; avoid breathing vapors from mixing solutions outdoors indoors instead use fans around the work area if possible; wash hands thoroughly after handling this material before eating lunchtime snack
How Often Do You Apply Insecticide For Alfalfa Weevils
This frequency of application is ideal because it will keep the insecticide applied at the proper rate and prevent it from drying out, which would cause the chemicals to break down or lose effectiveness.
The number of times you need to spray alfalfa weevil-infested plants depends on how severe the infestation is. If it is mild, one treatment each year should be sufficient; if it is moderate or severe (meaning there are many larvae), then two treatments each year may be necessary: one in early spring and another in late summer/early fall (July through September). The optimal time for these treatments would be when the weather isn’t too hot so as not to kill off beneficial insects such as ladybugs that help keep aphids under control.
The best time to apply insecticide for alfalfa weevils is early in the morning when temperatures are still cool and when there is plenty of moisture in the air (but not raining). The insecticide should be applied to the plant, stem, leaves, and soil. The insecticide should also be sprayed directly onto the roots of your alfalfa plants. The goal is to get as much of the chemical onto them as possible while they are still active and moving around.
Dosage Of Application
Insecticide application rates vary by insecticide, but most are applied in the spring and fall. The amount of insecticide you should use will be on the label of your product. If you’re unsure about how much to buy or what to spray with, ask around at your local agricultural supply store or farm supply store owner. They may be able to help you find a product that works best for your situation and budget range.
Effects Of Insecticide On Alfalfa Weevils
Insecticides are commonly used on alfalfa fields to help control the alfalfa weevil. They may be applied as a spray, drench or granular product.
Insecticides can kill alfalfa weevils and reduce their numbers. However, there are many different insecticides that have different effects on the alfalfa weevil. Some insecticides will kill only the adult stage of this pest while other chemicals will also kill larvae during their development inside plants or soil.
The best way to protect your crops from damage by alfalfa weevils is to use an insecticide that will provide long-term protection against pests like these destructive pests without causing too much harm to beneficial insects like bees or butterflies who are important pollinators for our agricultural industry
You could try natural methods to control them.
You could try natural methods to control them. If you have a soft spot for organic farming and traditional practices, then you may want to try some of these methods first.
You could use a combination of all three methods. Traditional weevil traps can be paired with biological controls like predator insects or nematodes, and then pesticides added at the end if necessary. This way, your options will be open until the very end if needed.
You can also use pesticides but this is the last resort for experts only. It’s always better if you can do something yourself instead of spending money on expensive products that may not work well anyway (and might even harm other organisms).
The mixture of insecticidal soaps and neem oil is another highly rated natural way of controlling Weevils on the Alfalfa field.
You could use pesticides but this is the last resort for experts.
Most people don’t have the training or expertise to use pesticides correctly. That can be dangerous, especially if you accidentally spray pesticides inside your home or on your car. If you do try to use a pesticide for alfalfa weevil control, make sure that you are following all directions closely and wearing gloves and protective clothing like long sleeves and pants.
It’s also important to remember that some insecticides can be harmful to humans and pets if they’re used incorrectly or accidentally ingested (e.g., by children). Insecticides are generally not recommended for home use because they may be ineffective at controlling pests in gardens like alfalfa weevils, or worse yet, they could actually cause more harm than good by creating resistance in these types of insects over time.

Pesticides: If you can’t find or don’t have time to make your own solution, then pesticides are the next best thing. There are several different types of pesticides, but one of the most common ones used for alfalfa weevil control is spinosad. Spinosad can be applied as a liquid spray or granules on the soil surface around your plants. You should only use this method as a last resort though because it will kill beneficial insects like ladybugs and lacewings which may already be in your garden.
Natural Methods: As far as natural methods go, an experiment done by North Dakota State University showed that hot pepper wax was more effective at repelling alfalfa weevils than DEET (the chemical found in most mosquito repellents).
Biological Control: Biological control of alfalfa weevil is a pest management approach that uses natural predators and parasitoids to reduce the population of the pest. One of the most effective biological control agents for this pest is a parasitic wasp, which lays its eggs in the weevil’s body. The eggs hatch and the wasp larvae feed on the weevil’s internal organs until they emerge as adults.
