Comprehensive Control Measures of Citrus Leaf Leaf Moth
Citrus leaf leaf miner: larvae sneak into young leaves, tender shoots subcutaneously to form a curved tunnel, and the damaged leaves curl and fall. Seedlings and young trees suffer heavy damage. Physical control measures During the summer and autumn shoots, shoots must be controlled in time to remove shoots that are too early and too late, and the shoots should be put out uniformly, and the fertilizer and water should be strengthened to ensure that the summer and autumn shoots are neat and robust. Citrus fruit trees generally do not leave summer shoots. When they choose to stay in autumn shoots, they avoid the peak period of egg laying. In winter, the combination of clear gardens is used to trim the damaged leaves and branches, and the litter is concentrated and burned to reduce the source of overwintering insects. The natural enemies of the citrus leaf miner are abundant in resources. In recent years, many orange groves have used natural enemies to control the leaf miners and achieved very good results. To protect and utilize natural enemies, we must make good predictions and predictions of insect pests and reduce the number of sprayings as much as possible. On the other hand, we must rationally use low-toxicity and low-residue pesticides, such as dimehypo and pyrethroids. At the same time, because natural enemies such as parasitic wasps emerge in the morning, spraying time is best chosen in the afternoon or evening. The natural enemies of leaf miners are mainly Asian and African grasshoppers, white-winged wasps, and predatory ants. Chemical control measures Do a good job in forecasting and forecasting insect pests, do a good job of investigating the law of the growth and decline of leaf miners in the field, and control the spraying of the larvae during the peak of hatching. Generally when the shoots grow to 3mm in summer and autumn, or when 50% of new shoots are taken out, the first drug is sprayed to prevent and control adult worms. In the evening, it is sprayed 2~3 times, once every 6~7 days until Newly wooded. If young larvae that have infiltrated into the leaves are sprayed at noon, the use of pyrethroids in the medicines is effective. Pay attention to different types of drugs to be applied during spraying, and it is best to add “new high fat film†to avoid drug resistance. Maintenance tree control measures (1) In winter, the Qingyuan Garden cut off the damaged branches, and the whole garden was sprayed with the “General Tree Guardâ€, which was sterilized and sterilized to reduce the number of overwintering insect populations. (2) Each time the shoot is released, the shoot must be controlled to stop the food of the leaf miner and reduce the chance of insect accumulation. (3) Use the low peak period of leaf miner to release. (4) Chemical control, can be sprayed in the summer, autumn shoots, tip length of 0.6 to 1 cm when the "new high fat film" + fungicide + insecticide ratio solution, spray every 7 to 10 days, continuous spray 2 or 3 times to protect the growth of new shoots. Most products of Fluorine-containing Benzonitrile is a colorless transparent liquid and has a pungent odor. It was widely used in pesticides, pharmaceuticals liquid crystal material manufacturing. High efficiency, low toxicity and residue characteristics. Through extensive research and production practice, we have found some good manufacturing processes of fluoro-containing cyanophenyl products. In addition, we have groundbreaking research on ratio of raw materials, solvent selection, the choice of solvent concentration, related use of catalysts..
