Problems solved by technology

[0003] There are many chemical pesticides on the market for the control of rice planthoppers, but there is no physical control method for rice planthoppers using photocatalysis. The damage of rice planthoppers to rice is not only directly stabbing and sucking juice, which hinders growth, and in severe cases, rice clusters form. In addition to wilting clusters and even causing the dead stems of the whole field to fall, the oviposition will also stab the plants, destroy the conduction tissue of rice, hinder nutrients and spread viruses, resulting in reduced or even no harvest of rice. In the requirements of organic ecological planting, it is forbidden to use any Therefore, it is necessary to provide a physical control method for rice planthopper damage

Embodiment Construction

[0014] 1. Material preparation: 600g of raw material Ⅰ, 70g of nano-titanium microspheres with shell-core structure as raw material Ⅱ, 100g of silicon dioxide as raw material Ⅲ, 100g of fermentation strain; among them, 300g of acetic acid and 300g of honey as raw material Ⅰ, and the fermentation strain of Monascus 80g, composed of 20g Streptomyces flavinus;

[0015] 2. After mixing and stirring the raw materials Ⅰ, put in the fermentation strains for 7 days of aerobic fermentation, the fermentation temperature is 28-30°C, and during this period, stir clockwise for 0.5H and counterclockwise for 0.5H at 6-7 every morning;

[0016] 3. After step 2 is further fermented, put into the nano-titanium microspheres of the core-shell structure of the raw material II, mix and stir for 1 hour, and keep the temperature at 55°C during the period;

[0017] 4. After step 3 is completed, add the silicon dioxide of the raw material II, mix and stir for 2 hours, and keep the temperature at 55°C d...

Abstract

The invention relates to a nano titanium rice planthopper control agent and a preparation method thereof. The nano titanium rice planthopper control agent comprises the following ingredients: 70 g of nano titanium microspheres with a shell-core structure, 100 g of silicone dioxide, 300 g of acetic acid, 300 g of honey, 80 g of monascus and 20 g of streptomyces microflavus. The action mechanism of the nano titanium rice planthopper control agent is as follows: burning rice planthopper larva and eggs to break the protective membranes and cell walls of the rice planthopper larva and eggs by using a photocatalytic reduction and oxidation function of nano titanium, and charging the alkaloid of the monascus and the streptomyces microflavus through the wounds to enter the cells of the larva or the eggs to break the cells. According to the nano titanium rice planthopper control agent and the preparation method thereof, the propagation of the rice planthopper is controlled by a physical method, harmfulness and toxic effects on human bodies are avoided, the resistance to drugs is not generated, and the nano titanium rice planthopper control agent is a safe, environment-friendly and non-toxic biological control agent.
