The invention provides a method for preventing and controlling tomato bemisia tabaci by using nesidiocoris tenuis, and relates to the technical field of pest prevention and control. The method comprises the following steps: S1, raising seedlings of tomatoes, and transplanting 20-25 days after raising the seedlings; s2, according to an intercropping mode that two rows of kidney bean planting belts are arranged every 3-4 rows of tomatoes, the kidney beans are arranged in a staggered mode and planted in different periods; s3, after tomato seedlings are planted, the density of the nesidiocoris tenuis in the kidney bean planting zone and the density of bemisia tabaci on tomato plants are monitored in real time, and the nesidiocoris tenuis is supplemented according to the monitored value; s4, performing field management. According to the method, the kidney beans and the tomatoes are intercropped, the kidney beans are used for providing a good survival and inhabitation environment for the nesidiocoris tenuis, good disease and pest prevention and control can be achieved in the whole growth period of the tomatoes, meanwhile, the yield of the tomatoes and the kidney beans can be improved, and economic benefits are increased.

This invention relates to the field of pharmaceutical preparation technology, specifically to a sulfachlorpyridazine sodium-methotrexate suspension, its preparation method, and its application. The sulfachlorpyridazine sodium-methotrexate suspension of this invention comprises the following components per 100 ml: 20-50 g of sulfachlorpyridazine sodium, 4-10 g of methotrexate, 0.1-0.25 g of suspending agent, 0.05-0.125 g of wetting agent, 0.2-0.5 g of antioxidant, 0.1-0.25 g of disodium edetate, and purified water to a final volume of 100 ml. The suspension prepared by this invention can delay the in vivo clearance of sulfachlorpyridazine sodium, prolong the synergistic effect time, and improve its bioavailability; in the treatment of coccidiosis infection in chickens and sheep, it can significantly improve weight gain, reduce intestinal lesion values, rapidly clear oocysts, and maintain a long-lasting protective effect after drug withdrawal.
