In the process of agricultural production, the excessive use of pesticides in excess of the range is the most important cause of the current residue of pesticides .
In order to prevent pesticide residues from exceeding the standard, it is recommended that farmers' friends must carefully read the pesticide labels when applying pesticides, and strictly follow the rational use of pesticides as specified in the label contents. Excessive application of pesticides means that the amount of pesticides used or the number of uses exceeds the pesticide registration label. This will not only increase the cost of medication; but it will also easily lead to excessive pesticide residues in agricultural products. At the same time, it will also enhance the resistance to disease, insects and grass.
Excessive use of pesticides will also lead to excessive pesticide residues in agricultural products. There are several possibilities: First, the amount of pesticide used is different; Second, the number of uses is different; Third, the time and season of using pesticides are different. Fourth, the safety interval and residue limit of the same pesticide on different crops are not the same.
Therefore, we should try to prevent the use of pesticides in an out-of-range range in agricultural production.
Tips for the Chinese pesticide network Xiaobian, you need to pay attention to three aspects:
First, choose qualified pesticide products from those shops with good reputation and regularity.
Second, strictly observe the use of pesticides in the control objects specified in the label on the pesticide bottle.
For example, isocarbophos is only allowed to be used on rice and cotton crops to control pests and cannot be used on other crops.
Third, for the varieties of pesticides that are frequently used, although they have the same pesticide name, their dosage forms and contents are different, and the objects to be cured and the amount and frequency of treatment are different. Never mix them. For example, the name is the same as the insecticide imidacloprid, which is also divided into wettable powders and suspending agents, but it is very different in the method of use. Some farmers have applied 600 grams per liter of imidacloprid suspension used in rice to crops such as cucumbers, which will eventually lead to excessive imidacloprid residues in cucumbers.
