How to use pesticides in tea garden? Be careful when using pesticides!

Because of its own characteristics, there are obvious differences between the use of pesticides and other crops, many pesticides are not suitable for use in tea gardens. Special attention should be paid to safety and rationality in the use of drugs in tea gardens. So how to use pesticides in tea garden?

I. rational selection of pesticides

Special attention should be paid to safety and rationality in the use of drugs in tea gardens. The so-called safe and rational use of pesticides requires good control of diseases and pests, safety to people, livestock, fish and tea, low residual toxicity, no pollution to the environment, no killing of natural enemies, and can prevent or delay the emergence of drug resistance. 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.

II. Reasonable selection of the period of medication

This is the key to rational drug use. The control of whitefly whitefly should be applied during the incubation period of larvae, the protection of natural enemies should avoid the peak emergence of parasitic natural enemies, and the safety interval of pesticide application should be strictly observed to avoid residual poison.

3. Adopt appropriate concentration

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.

IV. Mixed and rotation pesticides

Can prevent diseases and insects from producing drug resistance, at the same time play a dual treatment and synergistic effect, and to reduce the number of drug use. Rotational pesticides need to 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.

Tea pesticides should be used more carefully, not blindly use pesticides from other crops, it is best to use a small amount of medicine according to the actual situation of the tea garden, so as not to affect the quality of tea.
