How to prevent and control peanut bacterial wilt? The flowering and pegging stage is key
Peanut bacterial wilt is a devastating disease. Once infected, the whole plant wilts and dies, and it cannot be cured. The flowering and pegging stage of peanuts is the period when bacterial wilt breaks out, and during this time attention should be paid to spraying for control. Specific control method: when peanuts begin to bud, spray the leaves once every 10 to 15 days with a 1500-fold 70% hymexazol water-soluble...
Peanut bacterial wilt is a devastating disease. Once infected, the whole plant wilts and dies, and it cannot be cured. The flowering and pegging stage of peanuts is the period when bacterial wilt breaks out, and during this time attention should be paid to spraying for control.
Specific control method: when peanuts begin to bud, spray the leaves once every 10 to 15 days with a 1500-fold 70% hymexazol water solution, or a 600-fold 20% thiodiazole-copper water solution, or a 1000-fold 46.1% copper hydroxide water solution, evenly wetting all the leaves, until water droplets begin to drip down, and let it seep into the soil around the roots so that the soil around the roots is moist. Spray 2 to 3 times in succession. After all the peanuts have finished pegging, drench the roots once with an 800- to 1000-fold Bacillus subtilis water solution, applying 2 to 3 kg per sq m of peanut field, evenly drenched into the soil around the peanut plant roots. In this way, the peanut plants will not be infected with bacterial wilt, and they can flower, peg and set pods normally and achieve a high yield.
