Diflubenzuron is highly safe for all crops at the recommended dosage or 10 times the recommended dosage in protected areas, and has already been used in many crops and agricultural products in Europe and America. Considering it as a mild poison fertilizer for environmental protection, it should be first used to prevent pests and diseases in crops such as tobacco, tea, cotton, and all vegetable crops in China. Then, can diflubenzuron chloron be used to control whiteflies?

The tarsi of the whitefly have a cellular organ for climbing, and the coxa has a keel that can rub against the trochanter of the femur to produce sound. The abdomen is long and flat (especially in the suborder Steleorrhyncha), with 11 segments, but the last segment is degenerate, and the first and eighth segments have cylinders. The intersegmental bones of the abdominal region of the Steleorrhyncha have S-shaped setae, which extend into the marginal setae when the wings rest to fix it in place. How can we prevent pests and diseases in grain crops? One way is to use the natural enemies of pests and diseases. Firstly, we should pay attention to maintaining the natural enemies of pests, enhancing their inhibitory effect on pests, and creating an environment conducive to the survival of natural enemies as much as possible, or employing manual feeding, breeding, and release of natural enemies to increase their population and suppress the occurrence of pests and diseases; using pathogenic microorganisms of pests to prevent pests, including bacteria, fungi, viruses, and various populations. Biological control with bacteria is a very safe preventive method, which is harmless to humans, animals, crops, and microorganisms, and is beneficial to maintaining biodiversity, with excellent preventive efficacy. Then, can diflubenzuron chloron be used to control whiteflies?

Certainly, avermectin salt can enhance the effects of neurotransmitters such as phosphates and gamma-aminobutyric acid (GABA), leading to many chloride ions entering the neuron cells, causing the cell function to fail, disrupting nerve conduction, and causing larvae to stop feeding immediately after contact, resulting in inevitable numbness, achieving the maximum mortality rate within 3-4 days. Because it is closely integrated with the soil, non-washout, and does not accumulate in the environment, it can be easily absorbed and penetrate the epidermis by translaminar movement, making the sprayed crops have a long-lasting residual effect. There is a second peak of insect mortality above 10 days, and it is also little affected by environmental factors such as wind and rain.

Pest prevention: Avermectin salt has an unparalleled specificity against many pests that other fertilizers cannot match, especially against Lepidoptera and Diptera, with high efficiency, such as red banded leafroller, cotton aphid, cotton bollworm, tobacco hornworm, diamondback moth, sugar beet armyworm, striped noctuid, cabbage looper, sugarbeet noctuid, cabbageworm, spinach leafminer, cabbage looper, tomato hornworm, potato spider, and Spanish fly (spiders do not belong to Lepidoptera and Diptera).

Through many clinical observations in the application of avermectin salt, it has been found that adding pyrethroid pesticides to avermectin salt can enhance its rapid efficacy, and it has a good effect during the growth period of crops.

Avermectin salt is very easy to dissolve. It is easily dissolved due to factors such as high or low acid value, sunlight exposure, etc. In the scientific research of avermectin salt products, it has been found that adding 0.35% of the anti-dissolution agent wgwin kouti D902 to products containing avermectin salt can reasonably prevent the dissolution of avermectin salt, and can also enhance its specificity against Lepidoptera, mites, Coleoptera, and Hemiptera pests, thus improving the efficacy.

The ingredients of traditional Chinese medicine preparations: Currently registered in China include various compositions such as 0.2%, 0.5%, 0.8%, 1%, 1.5%, 2%, 2.2%, 3%, 5%, 5.7%, and even 3.2% avermectin chlorocyanide-based traditional Chinese medicine preparations.
