How do you control the plum fruit moth? Are there any good methods? I hope experienced readers can help explain.Plum fruits are often damaged by fruit moths during the fruiting period. Zhongdiwang has compiled control methods for the plum fruit moth, listed below for readers to reference.
Method one:Before the overwintering generation adults emerge from the soil (mid to late May), pile a 10 cm thick mound of soil around the tree base and tamp it down firmly so that the emerging adults cannot come out of the soil.
Method two:Before the overwintering generation adults emerge (after petal fall), spray the tree base with 75% phoxim emulsifiable concentrate at 0.5 kg per mu, or 40% dimethoate emulsifiable concentrate at 500 times dilution. After spraying, rake the soil evenly so the pesticide mixes with the soil and the insecticidal effect is improved. Before the physiological fruit drop of plums, ground control can be carried out by spraying the soil under the canopy once with 50% phoxim emulsifiable concentrate at 1000-1500 times dilution.
Method three:When the small fruits are the size of a wheat grain, spray for the first time. Dichlorvos, deltamethrin, fenvalerate or esfenvalerate can all be used. Spray once every 7-10 days; the effect is very good.
Method four:Biological control can be used to treat the soil under the canopy, such as Beauveria bassiana, or release young chickens in the orchard to control the insects.
Method five:Always keep the orchard clean and sweep up all fallen fruit, so as to reduce the source of insects the following year. In addition, growers in the same area should ideally carry out control in a unified way; this is an important factor determining whether control is effective.
