Fruit tree pest control
Diseases at the initial stage of pests and diseases should be controlled before the initial stage or epidemic center has spread and prevalence, and insect pests should be controlled before a small amount of occurrence occurs before a large amount of food has been started. The pests were controlled at the initial stage and spotting stage.
In the weakest period of pest activity activities, pests should be controlled before the third instar. At this time, the body size is small, body wall is thin, leaf volume is small, activities are concentrated, drug resistance is low, and drug killing effect is good. The disease is the best prevention and treatment period during the initial dip.
Pests are hidden and harmed The insect pests are sprayed on the surfaces of stems, leaves, flowers and fruits of the fruit branches in the early stage of control, and are easily exposed to death. Prevention and control of leaf roller moths should be preceded by leaf pests; prevention and control of heartworms should be in front of pods; prevention and control of pupa dry pests should be the best prevention and treatment period before or during drying.
Fruit trees with strong resistance to fruit trees are most likely to produce phytotoxicity during the bud and flowering stages, and they should be given as little or as little as possible. The prevention and control of the fruit trees during the period of suspension and dormancy are also the wintering periods of the diseases and insects. The latent places are relatively concentrated, and the worms are of the same age, which is conducive to the collective elimination.
