At present, jasmine infestation is heavy, which is characterized by shrinking and deformed young leaf shoots, gaps in flower buds, and biting of flowers. Farmers have entered a misunderstanding in their prevention and control, and they have no choice of timing and methods to spray pesticides indiscriminately. Increased production costs have unfavorable control effects and may also cause pesticide residues. Therefore, how to use pesticides scientifically and control pests scientifically ensure the healthy development of the jasmine industry in Yuanjiang County. Severe insect pests are caused by the use of pesticides for two reasons. First, long-term high-temperature droughts cause serious pest damage. Second, flower farmers have insufficient understanding of the consequences of pesticide residues. According to the weather forecast, pests will also increase, and we must do a good job of fighting against drought and pest control, and we must go out of the wrong way to grasp essentials and control insect pests and pesticide residues. I. Publicity and development of the impact of pollution-free jasmine and pesticide residues Most flower farmers in Yuanjiang County have insufficient understanding of green food and pesticide residues. We must conduct publicity and training so that the majority of flower farmers can fully understand the importance of developing green food. Jasmine has pesticide residues and Jasmine Tea Factory does not purchase it. The jasmine industry must fail and insist on eliminating pesticide residues. Second, a reasonable mix of mixed pesticides Most flower farmers anxious to achieve, a variety of pesticides mixed spray, increased production costs, pesticides may also be mixed chemical reactions, compliance, efficacy, counterproductive. There are three points to note when mixing: First, acidic pesticides cannot be used in combination with alkaline pesticides, and second, changes in the properties of mixed pesticide preparations occur, resulting in the formation of lumps or precipitates that cannot be used in combination: The third is to use mixed plants to cause harm to plants. Can not be mixed. Third, choose a good variety of pesticides to use high efficiency, low toxicity, low residue, pollution-free pesticides. It is forbidden to use pesticides that are banned from the use of high-toxicity, high-residue pesticides. They include chlorpyrifos, omethoate, panacea, and methamidophos. The main types of pesticides recommended for jasmine use are: Chlorampin EC, Dorabao, Cascicide, Ketite, Broom, Nissolant, Oxime, Uranus, Abantin, Afortin, Rui Jin Teng, Kung Fu, BT Emulsion, CPT, Bai Shu De, Chinese and Western Medicine Chrysanthemum Paste, Vegetable Hi etc. 4. The correct application time is 10:00 AM every day, after 6 PM is the peak of jasmine pest activity. When the application of pesticides is the best. The second is to strictly control the frequency of application and the amount of pesticide application. When the density of insect population is more than 5%, the pesticide should be sprayed and prevented, and it should be controlled every 10-15 days.
