Control of tea coir moth with pomegranate disease
1. Artificial prevention and cure
The coir sac hanging from the branches was removed manually and destroyed centrally. It is more convenient to carry out the dormant period of fruit trees, but attention should be paid to the protection of natural enemies. This method has a complete control effect and is safe for pomegranate, but it is time-consuming and labor-consuming because of its large orchard area.
two。 Chemical control
The key to chemical control is the selection of chemicals and the mastery of the appropriate period of control. Due to the pomegranate tree is more sensitive to chemicals, slightly careless, easy to cause drug damage. However, the pests are protected by coir sac, and the general pesticides are difficult to control, so the insecticides should be safe to pomegranate trees, no side effects, high efficiency, low toxicity, low residue, strong internal absorption and permeability. The control time should be the harm before the 4th instar of the larvae in order to achieve the ideal control effect. We conducted a control experiment and demonstration in Huanglian Zhangtulin pomegranate orchard, and selected the following three pesticides to control pomegranate tea coir moth, but also safe to pomegranate trees, which can be selected.
2.1 1000 times of the biological pesticide EC was sprayed at about 10:00 before the 4th instar of the larvae. The control effect of one dose was more than 95%.
2.2 1500-fold spray control of 10% high-efficiency Baike EC produced by cyanamide company. The knockout speed of the drug is fast, and the prevention and control effect of one time is more than 97%.
2.35% Regent suspension 2000 times liquid spray control, the efficacy of one-time use is more than 95%.

1. Ploughing and weeding. Weeds occur seriously in the orchard in summer, competing with fruit trees for water and fertilizer. Mid-tillage can not only remove weeds (chemical removal can be taken if necessary), but also loosen the soil and prevent soil moisture from evaporating. However, the root system of fruit trees in this period is exuberant in order to prevent
