Pesticide selection of the five major misunderstandings, what are they?
The use of pesticides is related to the quality of agricultural products and safety of a key link, whether from the perspective of food hygiene and safety and ecological environmental protection of the natural environment, or from the agricultural products to participate in the market competition, we all need to focus on the use of pesticides in China's management methods to enhance the overall level of scientific research on the use of medicines in China.
The use of pesticides to control plant diseases, pests and weeds, effective and rapid, has long been accepted by many villagers people. But because part of the people of the lack of basic knowledge of pesticides, especially on the pesticides of good varieties, new formulations and their control objectives, methods of operation and other issues such as the lack of awareness, in the actual use of five aspects of misconceptions.
One, do not distinguish between prevention and control objectives, see the drug used.
Some of the insecticide control of plant diseases, some of the fungicide used to control pests, and even herbicides used to control pests, especially in the case of pesticide supply shortages, such cases are particularly serious. That does not ask questions, blindly follow the trend of using drugs, light delay opportunity, jeopardize the actual effect, heavy lead to fertilizer, and even food crop extinction.
Two, heavy treatment light prevention, can not see the pests and diseases do not spray.
General conditions, the low age of the infantile insect resistance to pesticides is poor, accompanied by the age of the insect to increase its resistance to drugs is also accompanied by an increase. As a result, the control of pests to the larval stage or larval start station period is reasonable. And some farmers often in the insect pests have been big when the gradual use of drugs, has led to certain harm, and at the same time the actual effect of the drug can not give full play to; in plant disease control, do not understand the efficacy of the fungicide method, regardless of defensive fungicides, or curative fungicides need to wait for the problem of the emergence of the fungicide and fashionable before spraying, which led to the funding of the budgetary damage, but also does not have the effect of preventing disease.
Three, casually increase the value of drug concentration.
Some people do not mix the liquid according to the proportion, without professional measuring instruments, only with corkscrews or other non-standard containers, there is no total number of definitions, generally much more than the required concentration value, not only lead to consumption, and it is easy to produce fertilizer, at the same time, also make the resistance of the disease and insect to increase.
Four, the use of a single species for a long time.
In the use of pesticides once found that a certain type of pesticide effect is very good, on the use of a long time, even if the drug was found on the control of the actual effectiveness of the disease and insect control is reduced, are not demolition and change the type of method, but only to increase the amount of use, understand not on the disease and insect resistance has long been formed, but still expanding the dosage, which led to the vicious circle.
Fifth, confused with the definition of hazardous chemicals, the lack of security consciousness.
The current stage of high-quality pesticides are in the direction of, microtoxic, low residue angle development trend, and many farmers incorrectly feel that the toxic side effects of the fruit on the line, only to subscribe to the hazardous chemicals pesticides, microtoxic pesticides and lack of understanding of the pests and diseases of the lack of understanding of the pesticides in the use of pesticides are not in accordance with pesticide testing standards for use of pesticides will be prohibited in the peach tree, vegetables and fruits, and raw food crops to use pesticides to use on this kind of crops, which led to the result that people and animals are poisoned. and animals were poisoned.
