Bean planting: how to prevent and control heart bugs?
How to control heart worms in the process of planting beans? Please introduce the prevention and control methods. The adults lay eggs on the tender leaves of the plant. After 5-7 days, the hatched larvae eat into the pods to feed on the beans. After the 3rd instar larvae drill into the pods, it is difficult to kill them by spraying. Therefore, the control of the pest should strengthen fertilizer and water management to ensure neat growth and relatively concentrated flowering and podding period, so as to centrally eliminate the pest in the critical period. The principle of "controlling buds first" should be adhered to in the control of bean borer, and the larvae in the buds should be sprayed during flowering. The best time to spray is at 8: 10 a.m. on a sunny day (when the bud is open). Spraying once when the pods grow into more than 10 cm after flowering can kill the young larvae that are newly hatched and decayed into the young pods.
