How to prevent and control peanut bacterial wilt? These methods must be mastered
The period of peanut flowering and peg penetration is the outbreak period of peanut bacterial wilt, and during this period attention should be paid to spraying for control. Control method: when peanuts begin to show buds, spray the leaf surface once every 10-15 days with a 1500-fold 70% hymexazol aqueous solution, or a 600-fold 20% thiodiazole-copper aqueous solution, evenly wetting all leaves, until water droplets begin to...

Control method: when peanuts begin to show buds, spray the leaf surface once every 10-15 days with a 1500-fold 70% hymexazol aqueous solution, or a 600-fold 20% thiodiazole-copper aqueous solution, evenly wetting all leaves, until water droplets begin to drip down and penetrate into the soil around the roots, so that the soil around the roots is moistened. Spray continuously 2-3 times. After all peanut pegs have penetrated, drench the roots once with an 800-1000-fold Bacillus subtilis aqueous solution, applying 2-3 kg per sq m of peanut field, evenly drenching the soil around the peanut plant roots.
