Fruit is an important way to supplement nutrients in our daily life. In the process of fruit planting, some pesticides will inevitably be used. How can we improve the efficacy of pesticides in orchard? This article will introduce the methods to improve the efficacy of pesticides in orchards.

1. Do a good job of predicting and predicting the right medicine. According to the occurrence of pests and diseases, systematic observation of fixed orchards, using new technologies such as sexual attractants, black lights, insecticidal lamps, etc., to conduct pest and disease reporting, timely and accurately provide disease and pest occurrence for fruit farmers. Enable the fruit farmers to accurately grasp the spraying time and the object of prevention and treatment, to achieve the right medicine, and prevent it in a timely manner. At the same time, we must organize all households to achieve unified prevention and control. Linkage on the surface to improve the control effect. Due to the wide variety of pesticides, the pesticide responses of various fruit trees are different, and symptomatic pesticides are selected for the control objects. For example, methyl thiophanate in the fungicide is effective against round rotten fruit, and is ineffective against spotted leaf disease. In the insecticide , the pyrethroid pesticide is effective against the leaf-eating pest of the hazelnut, and the effect on the alfalfa is poor or basically ineffective.

2. Proper control. Different pests and diseases should be selected for different control periods in order to receive good control effects. It is best to use the pesticide in the sensitive period of the pesticide, and it is better to apply the egg and the newly hatched larvae. For example, the control of the larvae of the larvae of the larvae is better than that of the larvae of the first 1-2 years old, and the spraying should be carried out in the initial stage and the initial stage, especially after the onset of protective fungicides. . For example, the rotten fruit disease should be sprayed 7-10 days after the apple Xiehua to prevent the infection of the bacteria.

3. Scientific medication. In the process of pest control, it is necessary to change the traditional concept and make safe, economic and effective drugs according to the prevention and treatment indicators. It is necessary to cure less, cure early, pick and cure, and reduce the number of sprays and the amount of medication. The aim is to save pesticides, reduce costs and reduce pollution to the environment and fruits. At the same time, it is necessary to rationally mix pesticides according to the actual needs of pest control, according to the nature and efficacy of pesticides, to expand the control object to delay the resistance of pests and diseases, and improve the control effect. In addition, do not use a certain pesticide for a long time, and it is best to use one pesticide within one year. No more than 2 times.

4. Guarantee the quality of the spray. In order to give full play to the efficacy of the drug and improve the control effect, it is necessary to spray evenly in the process of making the drug, and the drug is comprehensive, and the atomization should be fine, and it should be done under the tree and then the inner periphery. It must be sprayed inside and outside, and the branches should be treated with drugs, especially for disease prevention and micro-infestation. Do not use the spray gun to make the medicine, not only the atomization is bad, the dosage is large, and the distribution of the medicine liquid is uneven, and the control effect is poor. In addition, the intensive canopy orchard should be reconstructed to achieve ventilation and light transmission, and the spraying is convenient.

5. Improve the quality of fruit farmers. Farmers should learn to master the comprehensive techniques of fruit tree pests and diseases, prevention methods and pesticide knowledge, and improve their own business quality in order to adapt to the development of market economy, enhance the ability to distinguish difficult problems and true and false pesticides, and avoid being misled. . For pesticides and new products that do not know the active ingredients, you can consult the technical department and do not use them indiscriminately. The control records issued to the production and distribution departments cannot be copied, and targeted drugs should be used according to the actual situation of pests and diseases.
