Embodiment approach

[0015] In one of the technical solutions of the present invention, the insecticidal composition is an emulsifiable concentrate preparation, and the mass percent of the components is:

[0016] Active ingredient A0.1~50%

[0017] Active ingredient B1~75%

[0018] Conventional emulsifier 10-30%

[0019] Conventional solvent 20~50%

[0020] Conventional synergist 1~5%

[0021] The specific production steps of the emulsifiable concentrate preparation are firstly adding the active ingredients A and B into the solvent to dissolve completely, then adding the emulsifier and the synergist and stirring evenly to form a uniform and transparent oily liquid, filling it, and then the composition of the present invention can be made cream preparations.

[0022] In the second technical solution of the present invention, the insecticidal composition is a suspension concentrate, and the weight percentage of the components is:

[0023] Active ingredient A0.1~50%

[0024] Active ingredient B...

example 1

[0082] (1) Test drug

[0083] 85% lepimectin and 95% tebufenozide are provided by Qingdao Hailier Pharmaceutical Group R&D Center.

[0084] Dissolve the original drug with acetone first, and mix the appropriate amount of the two original drugs into 5 different ratios according to the results of the preliminary experiment, and then use acetone to dilute each treatment into 5 series of concentration gradients for use.

[0085] (2) Test target

[0086] Beet armyworm reared for generations indoors, indoor conditions: temperature (26±2)oC. The relative humidity is 70%±5%, and the photoperiod is 16 / 8h (L / D).

[0087] (3) Test method

[0088] The spot method recommended by NY / T1154.1-2006 was used for determination. Clean the micro-dropper with solvent and adjust the dropper to the standby state. Use a brush to select neat and consistent test insects and use CO 2 After mild anesthesia, place it in a 9cm petri dish, and then use a micro-dropper to drip the drug on the abdomen of...

example 2

[0106] (1) Experimental test agent

[0107] 85% lepimectin original drug, 90% methoxyfenozide, the above original drugs are provided by Qingdao Hailier Pharmaceutical Group.

[0108] (2) Test target

[0109] Beet armyworm reared for generations indoors, indoor conditions: temperature (26±2)oC. The relative humidity is 70%±5%, and the photoperiod is 16 / 8h (L / D).

[0110] Experimental method is the same as activity determination example 1

[0111] (3) Toxicity test results and analysis:

[0112] Table 2 Indoor determination results of lepimectin and methoxyfenozide against beet armyworm

[0113]

[0114]

[0115] It can be seen from the table that in the mixing of different proportions, the co-toxicity coefficients are all greater than 120, showing a certain synergistic effect, wherein the synergistic effect of lepimectin: methoxyfenozide is 5: 13 is the most obvious, The co-toxicity coefficient was 154.48. The test results showed that both lepimectin and methoxyfeno...

Abstract

The invention relates to a pesticidal composition in the field of pesticide compounding, which contains effective ingredients of biological pesticide lepimectin and diacylhydrazine pesticide that are blended, wherein the weight percentage of the two effective ingredients is 0.1-50:75-1, and preferably 0.1-25:30-1; the total mass percentage of content of the effective ingredients in the pesticidal composition is 1% to 80% and preferably 1% to 30%, the balance is auxiliary elements which are allowed to be used and acceptable in the pesticide, and the pesticidal composition can be prepared into missible oil, a suspending agent, wettable powder, water dispersible granules, emulsion in water and microemulsion by using a known method; and the pesticidal composition taking the biological pesticide lepimectin and the diacylhydrazine pesticide as the effective ingredients has remarkable control effect in preventing and controlling lepidoptera insects such as diamondback moth, spodoptera exigua, spodoptera libra, heliothis armigera, chilo suppressalis and mealybug, and homopteran pests with sucking mouth parts such as plant hopper, aphid, aleyrodid and leafhopper.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, and relates to a dual compound insecticidal composition using biological pesticide lepimectin and bishydrazide compounds as active ingredients. Background technique [0002] The biopesticide lepimectin is a derivative of milbemycin (milbemycin) A3 / A4 discovered by Sankyo Corporation of Japan. It is used as a new type of insecticide for vegetables and fruits such as cabbage, tomato, citrus, strawberry and grape, mainly to control Lepidoptera and Homoptera and other pests. The drug has the characteristics of high insecticidal activity, less dosage, safe for humans and animals, no environmental pollution, strong specificity, no harm to natural enemies, and not easy to produce resistance, etc. It can be used in rotation with abamectin insecticides, In case of abamectin resistance. Therefore, it is known as one of the most promising broad-spectrum, high-efficiency, new non-cross-resist...
