Matters needing attention in the use of pesticides

1. Water quality

Do not use sewage dispensing, there are many impurities in sewage, the dispensing is easy to block the sprinkler, can also destroy the suspension of the agent and produce precipitation, and can not be dispensed with well water, which contains more minerals. When these minerals are mixed with pesticides, they are easy to produce chemical action and form precipitations. reduce its efficacy.

2. Concentration

It is not a pesticide with high concentration and high toxicity, it must be effective, if the concentration of the chosen pesticide is too high, it is not easy to volatilize, resulting in pesticide residues on crops. After eating, it will not only do some harm to the human body, but also damage the growth of crops, resulting in a reduction in yield in the later stage, which will also bring economic losses.

3. Time limit

The safety period of pesticides of different intensity is the same. During this period, you must know how long the pesticide safety period is, and do not spray before harvest. Generally, the residual period of highly toxic pesticides is about 60 days, and the residual period of high-efficient and low-toxic pesticides is about 15 days. Spraying before harvest is easy to cause food poisoning.

4. Mixed use

In the use of pesticides, must be mixed with other drugs in order to achieve the desired effect, but in the mixing, we must also pay attention to the requirements and standards, do not let the two drugs mixed together, adverse reactions.

5. Fog drop

The smaller the droplet, the better. The size of the droplet is related to whether it can be better distributed, deposited and spread on the target. If the droplet is too small, it will float in the air, and it will be difficult to deposit on the target, which will cause waste. If the droplet is too large, the liquid falling on the ground will also increase, and it will also cause waste.

Third, how to use the medicine box to hit the pesticide

1. Open the lid of the medicine box and add an appropriate amount of water to ensure the amount of a piece of land. Add pesticides according to the right proportion and according to the size of one mu of land.

2. Back the medicine box, carry the medicine box on the back, carry the two ropes across the shoulders and back on the shoulder. When spraying pesticides, the left hand presses the medicine box up and down to increase the pressure in the box, and the right hand holds the spraying rod to spray the vegetables.
