[0008] The disadvantage of lufenuron is that it kills insects slowly, so it needs to be used at the same time with insecticides that kill insects faster
In addition, lufenuron has a high cost and cannot be widely used in crop pest control
[0009] Long-term continuous single use of lufenuron or tebufenozide can easily lead to resistance of pests, leading to stronger and stronger resistance of pests, and even lead to rampant pests again, resulting in an increase in the amount of pesticides, which not only increases the cost of control, but also pollutes the environment, Reduced crop quality
In recent years, some major pests on vegetables in my country, such as diamondback moth, Spodoptera litura, Spodoptera litura, Pieris rapae, cabbage aphid, whitefly in greenhouse, etc., major pests of rice fields rice planthopper and major pests of cotton aphids, red spiders, cotton bollworm, etc. , have generally developed resistance to some conventional pesticide varieties, resulting in a significant decline in the control effect, and the pests are rampant again.

[0022] Weigh 1.06 g of lufenuron technical drug, 4.22 g of tebufenozide technical drug, 8 g of Nongru 2201#, 10 g of dimethyl sulfoxide, 5 g of acetone, 6 g of epichlorohydrin, 1 g of sorbitol, and the remaining amount of deionized water.
[0023] making process:
[0024] Add the original drug, dimethyl sulfoxide and acetone together to dissolve into a uniform oil phase; put Nongru 2201#, epichlorohydrin, sorbitol and deionized water into the emulsification dispersion tank, and form water under high-speed stirring Then put the oil phase into the emulsification and dispersion kettle, start stirring at the speed of 500-15000 rpm, the stirring time is 0.5-1.5 hours, and obtain uniform, transparent and stable 5% lufenuron by high-speed shearing · Tebufenozide microemulsion.
[0025] The process of preparing the microemulsion in the following examples is similar to Example 1.

Abstract
The invention relates to an insecticidal (acaricidal) composition having lufenuron and tebufenozide and application thereof. The insecticidal (acaricidal) composition mainly comprises the lufenuron and the tebufenozide and comprises an accessory ingredient and excipients, wherein the mass part ratio of the lufenuron to the tebufenozide is 10:1-1:50. The composition can be prepared into microemulsion, a suspending agent, aqueous emulsion, water dispersible granules, wetting powder or missible oil. The insecticidal (acaricidal) composition has a synergy effect, broadens pest prevention spectra,overcomes and stays the drug fastness of the pest, prolongs the service life of pesticides, and reduces the cost and the pesticide residue. The composition can prevent and treat Lepidoptera, Homoptera, Thysanoptera, Acarina pest (acarus) on crops, especially can prevent and treat diamond back moth, spodoptera litura, trialeurodes vaporariorum, rust mite and the like. The effect of the compositionis obviously better than that of two pesticides used separately.
Description
technical field [0001] The invention relates to a pesticide compound composition, in particular to an insecticidal and acaricidal composition with lufenuron and tebufenozide as main active ingredients. Background technique [0002] Lufenuron (Lufenuron), aliases: chlorfenuron, chlorfenuron, flupropoxycarbamide, chemical name: N-[[[2,5-dichloro-4-(1,1,2,3,3 , 3-hexafluoropropoxy)phenyl]amino]carboxy]-2,6-difluorobenzamide. Commodity name: Meiqu. [0003] Lufenuron is a benzoylurea insecticide and acaricide. It is an insect growth regulator. Its mechanism of action is to inhibit the synthesis of chitin in insects and affect the formation of insect cuticles to achieve the purpose of insecticide. Toxicity and contact action. [0004] Lufenuron is mainly used in crops such as corn, grapes, soybeans and vegetables. Lufenuron can be used to control diamondback moth, Spodoptera litura, Pieris rapae, Beet Spodoptera, Cabbage Spodoptera, Cotton bollworm, Thrips, Pod Borer, Rust Mi...
