The control of chemical pesticides has the characteristics of high efficiency and quick effect, but there are also drawbacks such as environmental pollution, pesticide residues, drug resistance formation and pest re-entry. Although the use of chemical pesticides is not completely ruled out in the current implementation of pollution-free oranges, it has also been proposed. higher requirement.
First, the use of pesticides should be emphasized in principle to minimize the use of chemical pesticides. The requirement for pesticides does not emphasize its “killing” effect, but focuses more on “regulation”, and prevention and control should be carried out according to the economic output value.
Second, in the selection of pesticides to use high efficiency, easy to divergence, strong selectivity, low water soluble pesticide species, prohibit the use of dicofol, fenvalerate and methamidophos in the production of oranges, stop the use of fenpropathrin , buprofezin, chlorimiphene, acephamide and other pesticides, promotion of the use of Su Yunjin stalk preparations (Tianba), Beauveria bassiana, tea stem borer and other biological pesticides and fish Teng ketone, matrine and other plant pesticides, the rational use of Lime sulfur. According to the current European Union standards, when the use of chemical pesticides is necessary, the use of herbicides such as sedans, phoxim, malathion, bifenthrin, deltamethrin, cypermethrin, and imidacloprid may be used. Tetracycline and other acaricide species.
Third, it is necessary to strictly follow the stipulations on the use of pesticides according to the standard of dose and safety intervals. Attention should be paid to the quality of the pesticide application and avoid the large loss of pesticides. To promote the use of pesticides. Organic chemical pesticides and botanical pesticides must not be used in organic orange gardens.
