There are three tips to fight drugs
In addition to drug timing, drug selection, and compounding, some skills are needed. 20 °C ~ 30 °C more effective drug fight Whether it is plants or insects or germs, 20 °C ~ 30 °C, especially 25 °C, is the most suitable activity temperature. At this time, fighting drugs will be more effective for the active pests and weeds and will be more safe for crops. Specifically, during the summer heat season, the time for fighting drugs should be before 10 o'clock in the morning and after 4 o'clock in the afternoon; the spring and autumn cool season should be selected before 10 o'clock in the morning before 2 o'clock in the afternoon; the greenhouse in winter and spring is best to choose sunny weather in the morning Fight drugs. Dosing time selection follows two principles After the liquid sprayed from the spray head is deposited on the target, it needs to be formed into a uniform film to cover the surface of the target to the maximum extent, thereby “masking†the pests and diseases on the target. From the deposition to the deployment, the liquid will be affected by many factors, including the air humidity. If the air humidity is small, the moisture in the medicine droplets will rapidly evaporate into the air, and even the liquid medicine will not spread on the target, which of course will Reducing the efficacy, even burning burning spots; In turn, if the air humidity is too high, the liquid deposited on the plant surface, especially the large droplets will easily condense into larger droplets, and twice Affected by gravity, the lower part of the plant will also produce phytotoxicity. Therefore, the time of day to fight drugs needs to follow two principles, one is that the air humidity is slightly dry, and the other is that the drug liquid can form a dried film on the surface of the target before sunset. The closer the nozzle is to the target than the better After the liquid sprayed from the nozzle, it crashed into the smaller droplets while colliding with the air and rushed forward. The result of the stumble was that the droplets were getting smaller and smaller. In other words, within a certain distance, the farther away from the nozzle, the smaller the droplets. Small droplets are more easily deposited and spread on the target. Therefore, it is not better to have the sprayer close to the plant. Generally, the sprayer of the backpack-type electric sprayer should be kept at a distance of 30-50 cm from the target, and the sprayer should be kept at a distance of about 1 meter. According to the performance of the sprayer and the sprayer, the spray nozzle can let the spray fog fall on the target. The efficacy will be better.
