Application of beauveria bassiana strain

Abstract

The invention discloses application of a beauveria bassiana strain to prevent and control of pests on food crops and application to preparation of a pesticide for preventing and controlling the pests on the food crops. The food crops are paddy rice, beans, potatoes, highland barley, broad beans or wheat; the pests are lissorhoptrus oryzophilus, corn borers, thorn-sucking insect whiteflies, aphids, pine caterpillars, grubs, locusts, potato beetles, monochamus alternatus, termites, tea lesser leafhoppers and peach fruit borers; a culture method of the beauveria bassiana strain comprises the following steps: inoculating the strain on a culture medium for culturing at the temperature of 25 to 30 DEG C for 5 to 10 days, and then obtaining activated spore powder. The beauveria bassiana strain disclosed by the invention has the advantages of high spore-producing ability, good production character and high growth speed; in addition, the beauveria bassiana strain has the characteristics of high toxicity, high insecticidal speed and environment friendliness; by using an insecticidal fungal preparation produced by the beauveria bassiana strain, the number of the population of the pests such as the lissorhoptrus oryzophilus and the corn borers on the food crops can be effectively controlled.

Description

technical field [0001] The invention relates to the field of agricultural biotechnology, in particular to the application of a strain of Beauveria bassiana. Background technique [0002] With the continuous improvement of living standards, people's requirements for food quality are getting higher and higher, and they are also paying more and more attention to food safety and environmental pollution issues. The production of pollution-free food and green food came into being. The safety of agricultural products is often a bargaining chip in international trade barriers, and green plant protection has also attracted much attention. Existing pests on food crops, such as rice water weevil, corn borer, piercing-sucking pest whitefly, and aphids have strong fecundity. For a long time, my country has mainly relied on chemical pesticides to control the above pests. Due to the large amount of chemical pesticides, The continuous application of pesticide residues in agricultural produc...

Existing pests on food crops, such as rice water weevil, corn borer, piercing-sucking pest whitefly, and aphids have strong fecundity. For a long time, my country has mainly relied on chemical pesticides to control the above pests. Due to the large amount of chemical pesticides, Year after year of application, agricultural products, soil and waters have been polluted by pesticide residues, which has constituted a serious threat and damage to human health; the enhancement of pest resistance has increased the amount of pesticides and doubled the cost of control; a large number of beneficial natural enemies have been damaged, and the ecological environment has been severely damaged. to severe damage, leading to rampant pest reintroduction
