Green beans are a commonly grown vegetable , but they are susceptible to many diseases during cultivation, especially bean virus disease, which is highly damaging and can cause severe outbreaks. So, what medicine can be used to treat bean virus disease? Let's find out below.
What medication is used to treat bean viral disease?
For the prevention and control of bean virus disease, you can use plant disease control agents, lentinan , morpholine guanidine hydrochloride, ningnanmycin, and virus A for spraying. In addition, at the early stage of bean virus disease, you can also spray with 1.5% alkanol·copper sulfate emulsion at 1000 times dilution, or 10% mixed fatty acid aqueous solution at 100 times dilution, or 20% morpholine·copper acetate wettable powder at 500-700 times dilution, once every 7-8 days, for 3-4 consecutive times.
Other prevention and control measures for bean virus disease
1. Disease-resistant varieties
To prevent bean virus disease, it is necessary to establish disease-free seed production fields, select disease-resistant varieties, carefully select seeds, and cultivate strong seedlings.
2. Seed treatment
To treat bean virus diseases, seeds are treated with dry heat or hot chemicals to deactivate the virus and reduce disease incidence in seedlings.
3. Implement crop rotation
To combat bean virus disease, crop rotation should be implemented to avoid continuous cropping, and fertilizer and water management should be strengthened, with increased application of phosphorus and potassium fertilizers. Diseased plants and leaves should be removed promptly to reduce the source of infection.
4. Reduce insect vectors
Early treatment of bean virus diseases is crucial, along with continuous aphid control to reduce insect-borne transmission. Upon discovery of aphids, promptly spray with pesticides such as imidacloprid, focusing on the undersides of the leaves.
5. Spray inhibitory drugs
Combining foliar nutrient sprays with drugs that inhibit and deactivate the virus source is more effective in controlling bean virus disease than using pesticides alone. In the early stages of the disease, spray a mixture of equal parts 0.1%–0.2% potassium dihydrogen phosphate, urea, and ordinary laundry soap (or black soap) 3–5 times consecutively, with an interval of 7–15 days between applications. Applying the mixture more frequently at the beginning and less frequently at the end helps promote plant growth and control the spread of the disease.
