Problems solved by technology

It has a very outstanding control effect on larvae. The disadvantage is that it has limited control effect on adults, no ovicidal effect, and weak systemic conduction effect.
[0005] Long-term use of one type of insecticide will easily lead to insect resistance, which will increase the amount of insecticide used, kill a large number of natural enemies of pests, increase the cost of insecticide, and pollute the environment, resulting in high toxicity, large dosage, large residues, and poor efficacy.
In the experiment of the inventor, it was unexpectedly found that the dual compound preparation of biopesticide lepimectin and benzamide insecticide can solve the above problems well, with less dosage, high control effect, and more environmental protection of biopesticide, and this type of pesticide compound With no relevant reports

Embodiment approach

[0015] In one of the technical solutions of the present invention, the insecticidal composition is an emulsion in water, and the weight percentage of the components is:

[0016] Active ingredient A 0.1~50%

[0017] Active ingredient B 0.1~75%

[0018] Emulsifier 3~30%

[0019] Solvent 5~15%

[0020] Antimicrobial agent 0.1~1%

[0021] Stabilizer 2~15%

[0022] Antifreeze 2~5%

[0023] Defoamer 0.1~8%

[0024] Thickener 0.2~2%

[0025] water balance

[0026] The specific production steps of the emulsion in water are as follows: first, the original medicine A and B, solvent, emulsifier, and cosolvent are added together to dissolve into a uniform oil phase; Pesticide auxiliaries are mixed together to form a uniform water phase; while stirring at high speed in the reactor, add the oil phase to the water phase, slowly add water until the phase inversion point is reached, turn on the shearer for high-speed shearing, and add the remaining water , cut for about half an hour t...

example 1

[0082] (1) Test drug

[0083] 85% lepimectin original drug, 96% chlorantraniliprole original drug, all of which 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] Rice planthopper. The rice brown planthopper was used as the test object. Insect species were taken from the paddy fields of Dalu Village, Zhaodian Town, Gaoqing County, and artificially reared for multiple generations in the insect culture room. The healthy and consistent 4th to 5th instar nymphs were selected for future use.

[0087] (3) Test method

[0088] The spot method recommended by NY / T 1154.1-2006 was used for determination. Clean the micro-dropper with solvent and adjust...

[0106] (1) Experimental test agent

[0107] 85% lepimectin and 98% bromotraniliprole, all of which are provided by Qingdao Hailier Pharmaceutical Group.

[0108] (2) Test target

[0109] Beet armyworm raised for generations indoors, indoor conditions: temperature (26±2) o C. 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

[0113]

[0114]

[0115] As can be seen from the table, in the mixing of different proportions, its co-toxicity coefficients are all greater than 120, showing a certain synergistic effect, wherein the synergistic effect of lepimectin: bromotraniliprole is the most obvious at 3:12, The co-toxicity coefficient was 134.21. The test results showed that both lepimectin and bromotraniliprole had higher activity ag...

Abstract

The invention relates to a pesticide composition in the field of pesticide preparation. An active ingredient of the pesticide composition is biopesticide lepimectin which is mixed with an amide pesticide serving as an active ingredient; the weight percentage ratio of the two active ingredients is (0.1-50): (75-1), preferably (0.1-25): (30-1); the total content of the active ingredients in the pesticide composition in percentage by mass is 1-80%, preferably 1-30%; other components are allowed and acceptable auxiliary components in pesticides; the pesticide composition can be prepared into missible oil, suspending agents, wettable powder, water dispersible granules, emulsion in water and microemulsion by a known method; and the pesticide composition taking the biopesticide lepimectin and amide pesticide as active ingredients is obviously effective in preventing and controlling Lepidoptera insects such as plutella xylostella, beet armyworm, prodenia litura, cotton bollworm, chilo suppressalis, mealybug and the like as well as homoptera piercing-sucking mouthpart pests such as plant hoppers, aphids, aleyrodids, leafhoppers and the like.

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 amide 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-resistance in...
