With the release of the most stringent pesticide residue standards, the tea garden medication is becoming more and more standardized. How to rationally use pesticides in tea gardens, the key point is to start from the safe and pollution-free side, the second method is correct, beware of phytotoxicity, and again look at the control effect. China Pesticide Network Xiaobian compiled the information on how to use pesticides rationally in tea gardens for your reference.
To achieve safe and rational use of drugs, the most fundamental thing is to resolutely implement the principle of "prevention first, comprehensive prevention and control" and use pesticides from the perspective of ecology. On the basis of agricultural control, chemical control and biological control are combined and coordinated. In the actual production, we should start from the following aspects:
1. Rational use of pesticides. Choose high-efficiency, low-toxic, low-residue, safe and non-adverse effects on tea and natural enemies, and low-cost pharmaceutical products, master the characteristics of the drug and the target of prevention and treatment, and make targeted drugs.
2. Reasonable choice of application period. This is the key to rational drug use. For example, the control of black thorn powder must be applied during the incubation period of larvae; the protection of natural enemies should avoid the application of parasitic natural enemies in the prosperous period; to avoid residual poisons, the safety interval of application should be strictly observed.
3. Use the appropriate concentration, dosage and frequency of administration. Only the lowest effective concentration, the dosage and the minimum effective number can be used to meet the economic, safe and effective requirements, in order to save medicine, save labor, save costs, reduce residual poison, and benefit natural enemies. Do not increase the concentration and dosage of the drug at will, and avoid blind application.
4. Use appropriate application methods. According to the dosage form of the pesticide and the actual situation of the tea garden, an appropriate application method can be selected.
5. Properly mix and use pesticides. It can prevent disease and insects from developing drug resistance, and at the same time, it can simultaneously cure and synergize, and can reduce the number of medications. The pesticides for the round should be mastered with agents that have different toxicological mechanisms and do not produce cross-resistance. In addition, it is necessary to grasp that after the mixing of pesticides, no adverse chemical reactions and physical changes should be produced, and no phytotoxicity should be caused to the crops. For new pesticide varieties, whether they can be mixed or not, they should first be tested in the community and then promoted.
6. Correctly consider the effect of prevention and control. Do not unilaterally pursue the percentage of prevention and control. We must look at the prevention and control effects from the ecological point of view and the economic benefits of agricultural production. Do not rely solely on chemical agents, and do not unilaterally pursue high percentages of prevention and control.
Flow Control Peristaltic Pump provides flow range from 0.00011 to 2300mL/min with variable pump heads and tubings. It offers not only intuitive and clear interface with color LCD touch screen, but also advanced features such as flow rate calibration and anti-drip function for accurate flow transfer.
