1. Strengthen the selection of varieties. Rainy and continuous weather, the use of systemic, quick-acting and emulsifiable pesticides to control pests and diseases, the effect is better. Such as systemic pesticides Carbofuran, Lego and other insecticides, carbendazim, indigo, metalaxyl and other fungicides, glyphosate, grass, grass and other herbicides, after a few hours of application Most of the medicaments are absorbed into the tissues by the stems and leaves of the plants. Even in the case of heavy rain, the effect on the efficacy is not great. Fast-acting pesticides, such as most pyrethroid pesticides, have strong contact and fumigation effects, and have a high insecticidal effect a few hours after application. Dairy oil pesticides, such as 50% dimethoate, can form an oil film on the surface of plants to enhance the ability of pesticides to withstand rain.
2. Add an adhesive as appropriate. The adhesive can enhance the adhesion of the agent and improve the ability of the agent to resist rain washing. Adding adhesives according to different types of pesticides, powder pesticides can be added with appropriate amount of soy flour, flour, etc., wettable powders and water agents, emulsion pesticides can be added with water-soluble adhesives such as animal bone glue, resin, etc. Drug effect.
3. Improve the application of pesticides. According to the performance of the drug, suitable application methods such as the systemic insecticide carbofuran and omethoate can be used, and the root zone application method can be adopted to avoid rain washing. It can also be used according to the living habits of pests and diseases. For example, the leafhoppers that feed on the night can be applied in the evening, and the effect is better. For the nighttime and morning release of spores of Chinese cabbage downy mildew, choose morning application, the effect is very good, if you can catch the gap between the rain stop, grab the quick-acting pesticides, you can also get better results.
The conductive Pipette Tips are specially designed for automatic workstations and are made of medical grade conductive polypropylene (PP) material, and the tips are conductive. After the conductive tip is adapted to a specific automatic pipetting workstation, it can detect the liquid level, making the automatic sample addition more intelligent and precise.
Transparent automatic Pipette tips can also be called robotic pipette tips or micro tips; Yongyue Medical's pipette tips have been sterilized and are packaged with 96 pieces per box, which is easy to carry and operation; compatible for Beckman, Tecan, Rainin to achieve automatic pipetting performance and ensure the consistency of pipetting.
The robotic tip is made of imported polypropylene (PP) material, with high transparency. The surface is treated with a special process and has super-hydrophobicity to ensure the accuracy of experimental data. The product is automatically produced in a 100,000-level purification workshop, free of DNase, RNase, and pyrogen-free.
