Description

Technical Field

[0001] The invention belongs to the field of insecticides, and specifically discloses a synergistic suspension concentrate containing tetrachlorantraniliprole and application thereof. Background Art

[0002] Pesticides play an obvious role in preventing and controlling agricultural and forestry pests or urban health pests. According to statistics from international companies, it currently costs about 200 million euros and takes about 12 years to screen out a commercial compound from 160,000 synthesized compounds. This shows the difficulty of industrializing the independent creation of compounds. However, in the actual application process of agricultural production, the advent of a new pesticide compound, the most likely problem for pest control is the development of pest resistance. The faster the resistance develops, the shorter its life cycle. In addition, the pesticide utilization rate of my country's three major crops of rice, corn and wheat: 35% in 2013, 36.6% in 2015, 38.8% in 2017, and 39.8% in 2019. Among them: spatial transfer causes about 20% of the dose loss (droplet evaporation, drift, etc.); interface transfer causes about 35% of the dose loss (droplet bouncing, breaking, splashing, liquid loss, etc.). Therefore, improving the biological activity of new compounds and their rational use are key factors in extending the life cycle of created compounds. CN103238603 B mentions a method for preparing a tetrachlorantraniliprole suspension, the biological activity of which is slightly better than (or equivalent to) the original drug. With improper use and long-term use by users, obvious resistance has appeared in some areas in recent years. The purpose of the present invention is to increase the penetration speed and amount of the drug solution to the target, enhance the wetting effect of the drug solution and the amount of deposition on the target, reduce evaporation, and improve the actual effective utilization rate of the active component by matching an adjuvant system that is better than the tetrachlorantraniliprole active component, thereby enhancing its use effect, reducing the dosage, delaying the generation of resistance, and reducing pollution to the environment, thereby extending the shelf life of the compound and making it better serve the agricultural industrialization.

[0101] Biological Activity Test Example

[0102] Example 39: Indoor activity measurement

[0103] The test targets are corn borer (Ostrinia furnacalis Guenee), 3rd instar larvae; diamondback moth (Plutellaxylostella Linnaeus), 3rd instar larvae; armyworm (Mythimnaseparata walker), 3rd instar larvae; all are sensitive strains raised indoors. The test conditions are temperature: 24-26℃, humidity: RH 40-60%, light: L:D=14:10. The test preparations are accurately weighed with an electronic analytical balance and diluted with water to the required concentration of the drug solution. The original drug is first completely dissolved in the solvent, and then prepared with 0.1% Tween 80 water to prepare the required concentration of the mother solution, and diluted with water or Tween water according to the experimental design dose to a series of drug solutions with a certain concentration gradient. The test adopts the airbrush spray method. The test plant of diamondback moth is a small radish seedling, the test plant of corn borer is a corn stalk of uniform thickness cultivated in a greenhouse, and the test carrier of armyworm is a corn leaf, and the corn stalk and leaf are cut into small pieces of a certain length for standby use. The prepared liquid medicine was sprayed with an Airbrush manual sprayer in the order of the experimental design dose from low to high. After treatment, it was placed in a 6 cm diameter petri dish with filter paper to dry naturally in the shade, and standard test insects were inoculated, and a blank control was set up. The treated test materials were placed in an observation room, and the diamondback moth was investigated 48 hours after treatment, and the corn borer and armyworm were investigated 72 hours after treatment. The number of dead and alive insects was recorded, and the corrected mortality rate was calculated using the Abbott formula. The toxicity regression line and LC50 value were calculated using the DPS software.

[0112]

[0113] From the data listed in Tables 1 to 4 and the test index data in the examples, it can be seen that the test sample liquid has good wetting, spreading and penetration on the target, the liquid rebounds less on the target, the liquid holding capacity on the target is large, the evaporation is small, the absorption rate is large, and the biological activity is high. The finer the particles, the better the drug effect, and vice versa, the worse the drug effect.
