Problems solved by technology

The corn borer (Ostrinia nubilalis) is the main pest in corn production. It not only eats corn leaves, bores into corn main stems or ears, reduces photosynthesis, affects nutrient transport, but also produces various secondary diseases, resulting in reduced corn yields. The quality of corn has caused a loss of 7%-15% of corn production all year round. In serious years, the production has been reduced by more than 50%, or even completely eliminated, causing huge economic losses to my country's grain production.

Abstract

The invention relates to a suspoemulsion of Beauveria bassiana seed coating agent, which comprises the following components: 1.0 g of suspoemulsion and 50-100 g of corn seeds, which are evenly stirred and dried to be sown. It uses the symbiotic relationship between Beauveria bassiana and plants, and screens out a seed coating agent with high spore content, high spore germination rate, and efficient mechanized sowing of coated seeds. Insect resistance; It has growth-promoting and insect-resistant effects on corn, and can be mechanized sowing.

Description

technical field [0001] The invention relates to a beauveria bassiana seed coating agent and a preparation method thereof. A new formulation of microbial pesticide. Background technique [0002] Corn is the second largest grain crop in my country, with an annual output of more than 300 billion catties. It can be used for food, and can also be used as feed and industrial raw materials to produce industrial alcohol and shochu. The corn borer (Ostrinia nubilalis) is the main pest in corn production. It not only eats corn leaves, bores into corn main stems or ears, reduces photosynthesis, affects nutrient transport, but also produces various secondary diseases, resulting in reduced corn yields. The quality of corn has caused a loss of 7%-15% of corn production all year round. In severe years, the production has been reduced by more than 50%, or even production has ceased, causing huge economic losses to my country's grain production. [0003] Chemical pesticides have always play...
