Diseases And Pest Control In Onion Crop
The key diseases and pests that affect onion crops are:
- Verticillium wilt
- Fusarium yellows (infection by the fungus Fusarium oxysporum)
- Blackleg (Phoma destructiva), is caused by a fungal pathogen that attacks the vascular tissue of plants, causing them to be stunted and discolored.

How Fungicide For Onion Crop Works
Fungicide for onion crop consists of the active ingredient thiophanate-methyl and the mode of action is systemic.

This results in cell death and therefore stops fungal growth.
The target site is on fungi that cause brown rot, including Alternaria spp., Aspergillus spp., Botrytis cinerea, Ceratocystis spp., Fusarium oxysporum f.sp acuminatum (Foc), Microdochium nivale, Sclerotinia sclerotiorum (black rot).
The duration of effect varies by species with some being short-lived while others are long-lived at least 6 months depending on conditions like temperature and humidity levels during the application time window when weather conditions are suitable for disease development to occur

In addition, onions should be planted after soil moisture has been adequate for 10 days prior to planting, as well as being able to withstand drought conditions without wilting or dying out within 24 hours after planting time.
When using fungicide sprays on your onion crop, you will want to ensure that you are using the right application rate according to label instructions before spraying any product onto your plants so that they will not receive too much or too little of what they need from these applications throughout their lifespans which could otherwise lead up into some serious problems down the line if ignored properly enough.
