How to control the plum fruit moth? A detailed explanation of the latest control methods

During their growth, plums suffer from pests and diseases, and the most damaging among them is the fruit moth. It is a pest of the order Lepidoptera, family Tortricidae, and the damage is mainly caused by the larvae. The larvae bore into the fruit to feed, and after the fruit is damaged, fruit gum flows out of the wormhole, preventing the fruit from developing normally, and as time goes on, feces gradually are expelled from the wormhole, which can very easily cause the fruit to drop. So how should the fruit moth be controlled? Let's take a look together.

1. Winter orchard cleanup

Before winter arrives in the orchard, winter orchard cleanup should be carried out in a timely manner so the plants can overwinter safely. The cleanup work must be thorough: gather diseased branches, diseased leaves and diseased fruits on the ground and burn or deep-bury them in a centralized way. Diseased branches, diseased leaves and rotten fruits on the plants should also be pruned off and disposed of cleanly together. Then earth up and fertilize, and deep-plow the soil to destroy overwintering pests and eggs in the soil. Finally, spray the entire orchard with an orchard-cleaning agent to thoroughly sterilize and kill pests. This can reduce the degree of damage from the fruit moth and other pests and diseases.

2. Control under the tree

Before the overwintering adults emerge from the soil, earth up around the tree with soil that has been disinfected and sterilized, building a mound about 10 cm thick, and after earthing up, tread it firm so that emerging adults cannot come out of the soil in time. In addition, methods such as land preparation and weeding as well as scraping tree bark can be used to destroy overwintering sources of the pest. After earthing up, loosen the soil in time so as not to affect the growth of the plants. In addition, chickens can be raised under the trees in the orchard to feed on the pests, which can both reduce pest damage and produce pollution-free chickens.

3. Control on the tree

Control on the tree is generally carried out from the petal-fall stage to the young fruit stage, and it is best carried out when the amount of fallen flowers reaches about 95%, when the young fruits have just begun to grow and are the size of a grain of rice. This is also the period when the fruit moth lays eggs, and spraying 3000-4000 times diluted 0.8% abamectin or 1000 times diluted 48% chlorpyrifos for control gives a relatively good effect.
