Tea planting techniques: how do tea trees use pesticides?

How do tea trees use pesticides? Please give guidance on the use of pesticides in tea trees can refer to the following methods: 1. Reasonable selection of pesticides. Select the varieties of chemicals with high efficiency, low toxicity, low residue, safe to tea and natural enemies, no adverse effects and low cost, and master the characteristics and control objects of the agents. two。 Reasonable selection of pesticide application period. This is the key to rational drug use. For example, the control of whitefly must be applied during the full hatching period of larvae, the protection of natural enemies should avoid the peak emergence of parasitic natural enemies, and the safe interval of pesticide application should be strictly observed to avoid residual poison. 3. Appropriate concentration, dosage and times were adopted. Only by using the lowest effective concentration, dosage and effective times can we meet the requirements of economy, safety and effectiveness, and save medicine, labor, cost, residual poison and natural enemies. Do not increase the concentration and dosage of drugs at will, and do not apply drugs blindly. 4. Appropriate application methods were adopted. The appropriate application method can be selected according to the dosage form of pesticide and the actual situation of tea garden. 5. Properly mix and rotate pesticides. It can prevent diseases and insects from producing drug resistance, at the same time play a dual treatment and synergistic effect, and can reduce the number of drug use. Rotational pesticides should master the selection of agents with different toxicological mechanisms and do not produce cross-resistance. In addition, it is also necessary to know that the mixture of pesticides should not produce adverse chemical reactions and physical changes, and should not cause drug harm to crops. For the new pesticides, whether they can be mixed or not, the plot test should be carried out first, and then popularized. 6. The effect of prevention and control should be treated correctly. Do not unilaterally pursue the percentage of control, we should look at the control effect from the ecological point of view and the economic benefits of agricultural production, do not rely solely on chemicals, do not unilaterally pursue a high percentage of control.
