What medicine is used for Sclerotinia?

Recently, Sclerotinia sclerotiorum has become one of the hot topics in the agricultural field, and many farmers and growers are paying attention to how to effectively prevent and control this disease. Sclerotinia sclerotiorum mainly damages crops such as rapeseed, soybeans, and sunflowers. In severe cases, it can lead to reduced yields or even no harvests. This article will combine the hot content of the entire network in the past 10 days to give you a detailed introduction to the prevention and treatment drugs and usage methods of Sclerotinia sclerotiorum.

1. Dangers and symptoms of sclerotinia

Sclerotinia is a fungal disease caused by Sclerotinia sclerotiorum, which mainly damages the stems, leaves, flowers and fruits of crops. In the early stages of the disease, water-soaked lesions appear on the affected area, and then gradually expand to form a layer of white hyphae, and eventually black sclerotia. If not prevented in time, the disease will spread rapidly and cause widespread crop death.

2. Recommended drugs for the prevention and treatment of Sclerotinia sclerotiorum

According to the popular discussions and expert suggestions on the Internet in the past 10 days, the following are the commonly used drugs for preventing and treating sclerotinia and their effects:

3. Comprehensive prevention and control measures for sclerotinia

In addition to the use of chemical drugs, comprehensive prevention and control measures can also effectively reduce the probability of sclerotinia:

1.crop rotation: Rotate crops with non-host crops (such as wheat, corn) to reduce the accumulation of sclerotia in the soil.

2.Dig the soil deeply: After harvesting, plow the land deeply to bury the sclerotia in the deep soil to reduce the chance of their germination.

3.Reasonable dense planting: Avoid planting too densely, maintain ventilation and light transmission in the field, and reduce humidity.

4.Remove sick bodies: Timely remove diseased plants and debris from the field to reduce the spread of pathogenic bacteria.

4. Popular questions and answers

Based on recent popular discussions on the Internet, the following are frequently asked questions and answers about Sclerotinia prevention and control:

Q1: When is the best time to prevent and control Sclerotinia?

A1: The prevention and control of Sclerotinia sclerotiorum should be based on prevention. It is recommended to spray the crop before flowering or in the early stage of the disease. Spray once every 7-10 days for 2-3 times in a row.

Q2: Which crops are most susceptible to Sclerotinia sclerotiorum?

A2: Rapeseed, soybeans, sunflowers, lettuce, celery and other crops are prone to sclerotinia and require special attention to prevention and control.

Q3: What are the methods for biological control of Sclerotinia sclerotiorum?

A3: Biological agents such as Trichoderma spp. or Bacillus subtilis can be used to inhibit pathogenic bacteria through competition or antagonism.

5. Summary

The prevention and control of sclerotinia requires a combination of chemical drugs and agricultural measures to achieve the best results. When selecting drugs, it is recommended to match them appropriately according to crop type and disease severity, and to pay attention to rotation of drugs to avoid drug resistance. At the same time, strengthening field management and reducing the transmission routes of pathogenic bacteria is the key to preventing and controlling sclerotinia.

We hope this article can provide you with valuable reference to help you effectively deal with the threat of sclerotinia and ensure high and stable crop yields.
