Pesticide Use Methods in Pollution-Free Tea Production
Use of Pesticides in Pollution-Free Tea Production
(Agricultural Wealth Network) How to prevent and control pests and diseases in pollution-free tea gardens? In the process of pest and disease control, modern sustainable agricultural concepts should be applied, starting from the tea garden ecosystem, comprehensively applying various control measures, and promoting pollution-free control technologies. Pesticides must be used for control, with control plans prepared in advance, giving priority to biological pesticides and environmentally compatible pesticides, rationally using the chemical pesticides recommended in the pollution-free tea production regulations, and carefully keeping control records.
Pollution-free control measures: Pollution-free control measures for pests and diseases in pollution-free tea gardens include agricultural control, physical control, and biological control. Pollution-free control measures do not cause environmental pollution and do not lead to pesticide residue problems; therefore, they should be given priority.
Use of biological pesticides or environmentally compatible pesticides: Commercial biological agents: such as Bacillus thuringiensis BT preparation, tea geometrid virus preparation, tea tussock moth virus preparation, whitefly fungi, etc. Plant-derived pesticides such as toosendanin, matrine, nicotine, rotenone, pyrethrin, etc. Mineral-derived pesticides such as half-strength lime Bordeaux mixture, etc. They are the preferred preparations for pest and disease control in tea gardens in the future.
Rational use of chemical pesticides: Select appropriate pesticide varieties and formulations for the target pests. Strictly apply pesticides according to the specified dosage, application frequency, application method, appropriate application timing, safety interval, precautions, etc. It is advisable to use one pesticide for multiple targets or rational mixing of pesticides. The use of prohibited pesticides is strictly forbidden.
Attention to control thresholds and appropriate application timing: The pollution-free tea production technical regulations explain the control thresholds and appropriate control timing for major pests and diseases. Before chemical control, these should be carefully consulted.
Pesticide varieties for application: Highly efficient, low-toxicity, low-residue pesticide varieties may be used in a limited manner. It is prohibited to use highly toxic, high-residue pesticides such as DDT, BHC, parathion (1605), methyl parathion (methyl 1605), methamidophos, acephate, omethoate, sodium pentachlorophenate, chlordimeform, carbofuran, dicofol, isocarbophos, cypermethrin, fenvalerate and their mixtures.
Application method: Use conventional agricultural sprayers, selecting low-volume spraying. Spray over the canopy surface of tea bushes; for pests in the middle and lower parts of tea bushes, use side low-volume spraying. Application dosage and safety interval: Strictly control the application dosage and safety interval according to the requirements of GB4285, GB/T8321 (Appendix C: Pesticide Varieties Usable in Pollution-Free Tea Gardens and Their Safety Standards).
Use mineral-derived pesticides in non-production seasons: such as half-strength lime Bordeaux mixture, etc.

Pollution-free control measures do not cause environmental pollution and do not lead to pesticide residue problems; therefore, they should be given priority.
