Embodiment 1

[0018] Example 1 Indoor Toxicity Determination Experiment of the Main Insecticide of the Present Invention to Spodoptera litura

[0019] When measuring indoor toxicity, measure metarhizin and chlorpyrifos according to the mass ratio of metarhizine and chlorpyrifos at 5-1:5-9, and make a mother solution with a certain concentration with acetone and place it in the refrigerator (4°C) for later use , all agents were diluted with 0.01% Tween-80 solution during the experiment. The metarhizine is any one of metarhizin A, metarhizin B or metarhizin E, or a mixture of two or more in any proportion. Each treatment was replicated 3 times, and each replicate had 1 petri dish, and 15 third-instar Spodoptera litura larvae were placed in each petri dish. First cut the cabbage leaves into small pieces of 6-7cm, soak them in the liquid medicine for about 5 seconds, take them out, dry them indoors, put the leaves into a petri dish connected with Spodoptera litura, and use wet cotton balls to ...

Embodiment 2

[0024] Example 2: Indoor Toxicity Determination Experiment of Insecticide EC Compounded with 50% Metarhizin and Chlorpyrifos in a Mass Ratio of 2:8 to Spodoptera litura

[0025] The emulsifiable concentrate is diluted with water to the concentration gradient to be tested, and the experimental method is the same as in Example 1. The experimental results are shown in Table 2. The co-toxicity coefficient of the emulsifiable concentrate reaches 153.69, which has obvious synergistic effect.

Abstract

The invention discloses a pesticidal main agent compounding destruxin and chlorpyrifos, and the mass ratio between the destruxin and the chlorpyrifos is 5 to 1 : 5 to 9; and the invention also discloses a pesticide prepared by adopting the main agent. The invention adopts the highly effectively, secure and broad-spectrum azotic heterocyclic organic phosphorus insecticide and acaricide chlorpyrifos to be compounded with the insect pathogenic fungus destruxin with remarkable pesticidal effect, and the preferable mixed proportion between the destruxin and the chlorpyrifos is determined through experiments, therefore, a new compound pesticide is provided. The pesticide has a completely new function mechanism different form the prior pesticide, has an excellent pesticidal effect particularly in poisoning and killing prodenia litura with serious harms, and meanwhile is environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of biopesticides, and relates to a novel main insecticide compounded with metarhizin and chlorpyrifos and an insecticide. Background technique [0002] Spodoptera litura is an important omnivorous agricultural pest distributed worldwide. In recent years, the frequency of occurrence of large-scale pests in many areas of my country has increased significantly, and the damage has aggravated. Due to the long-term use of chemical pesticides, the insect has developed resistance to organochlorines, organophosphorus, carbamates, pyrethroids and other insecticides to varying degrees. Its harm is difficult to control. [0003] Chlorpyrifos is an efficient, safe and broad-spectrum nitrogen-containing heterocyclic organophosphorus insecticide and acaricide. It has contact killing, stomach poisoning and fumigation effects on pests. It can be used in rice, wheat, corn, soybeans, peanuts, cotton, Fruit trees, tea trees, ...
