Problems solved by technology

[0004] 1. The control of locusts only uses Microsporidia locusts or Metarhizium anisopliae, and the control of locusts cannot achieve the desired effect.
[0005] 2. The manual spraying of the usual prevention and control spraying method is not only inefficient, but also has high labor costs and is prone to inhalation hazards.
In recent years, the rapid development of aircraft spraying and drone spraying can effectively save labor, be efficient and safe, but the existing locust control agents are not suitable for aircraft spraying and drone spraying

Abstract

The invention discloses an ultra-low volume suspending agent containing nosema locustae and metarhizium anisopliae and used for grasshopper control as well as a preparation method of the suspending agent. The ultra-low volume suspending agent comprises raw materials in parts by weight as follows: 1-6 parts of metarhizium anisopliae spore powder, 1-10 parts of nosema locustae, 1-5 parts of a sulfonate anionic emulsifier, 0-5 parts of a non-ionic surfactant, 5-15 parts of vegetable oil, 50-90 parts of polyol and 0.001-0.1 parts of an ultraviolet protective agent. The ultra-low volume suspending agent combines nosema locustae and metarhizium anisopliae for use, so that respective defects of the nosema locustae and metarhizium anisopliae can be overcome, ideal control effect can be achieved, the flash point is high, volatilization is low, good liquidity is realized, requirements for ultra-low volume spray for the ground and an airplane can be met, phytotoxicity on plants is avoided, the environment is not polluted, the activity of spore and microsporidia can be better kept, the control effect is good, an aversion function is not produced, and antifeedant of pests is avoided.

Description

technical field [0001] The invention relates to a biological pesticide preparation, in particular to an ultra-low-capacity suspending agent for controlling locust microsporidia and metarhizium anisopliae and a preparation method thereof. Background technique [0002] Locusts are an important food pest. At present, my country still mainly controls locust pests by spraying organophosphorus highly toxic pesticides. However, the hazards of chemical pesticides, such as environmental pollution, are becoming more and more serious threats to health. It is of great significance to seek biological methods to control locust pests. In the control of locusts, the most mature application technology and the widest range are Microsporidia locusts and Metarhizium anisopliae. Among them, Microsporidia locusts germinate in the digestive tract after being eaten by pests, enter the blood cavity through the intestinal tract, and mainly infect the fat body, digestive tract, nervous tissue a...
