Peanut attention to control bacterial wilt

Peanut bacterial wilt is a devastating disease that cannot be cured once it is infected. During the flowering and falling of peanuts, it is the outbreak period of bacterial wilt. During this period, attention should be paid to spraying prevention.

Specific control methods: 1. Formulated fertilization technology, apply enough base fertilizer, increase phosphorus and potassium fertilizer, apply nitrogen fertilizer, and promote the stable and early development of peanut. Lime can be applied to acidic soils to reduce soil acidity and reduce disease occurrence. The diseased plants found in the field should be removed immediately, taken out of the field and buried with lime. When the peanuts are harvested, the diseased plants and residues are removed in time to reduce the soil pathogen. 2. Seeding with 50% carbendazim wet powder before sowing, the dosage is 0.12%~0.2%, and the seeds are mixed and mixed before seed dressing. When the peanuts start to bud, spray 1500 times 70% methicillin aqueous solution or 600 times 20% thiabend copper aqueous solution and 1000 times 46.1% copper hydroxide aqueous solution every 10~15 days to evenly spray all the leaves. At the beginning, water drops are dripped down and infiltrated into the soil around the roots to moisten the soil around the roots. Spray continuously for 2~3 times. After all the needles have been dropped, apply 800-1000 times of Bacillus subtilis aqueous solution to the roots, and pour 2~3 kg of peanuts per square meter, evenly drenched in the soil around the roots of peanut plants. In this way, peanut plants will not be infected with bacterial wilt, and they will be able to flower and pod pods normally and obtain high yield.
