Description

Technical Field

[0001] The invention belongs to the technical field of pesticides, and particularly relates to a pesticide composition containing fengzhisu and application thereof. Background Art

[0002] Plant growth regulators play a vital role in modern agriculture and horticulture. They can regulate the growth and development of plants and improve crop yield and quality. Traditional plant growth regulators are mostly prepared by chemical synthesis methods, but with the development of biotechnology, plant growth regulators from microorganisms have gradually attracted attention. Microorganisms have rich diversity and metabolic pathways and can produce a variety of substances with plant growth regulating activity. These substances have the advantages of high efficiency, low toxicity, and environmental friendliness, providing a new way for sustainable agricultural development.

[0003] Fengzhisu, also known as anisic acid, has a chemical name of 4-methoxybenzoic acid. It is an important organic synthesis intermediate and modifier. It is also an important raw material in the fields of preservation and pharmaceuticals. It is widely used in the medical, food and daily chemical industries. For example, anisic acid can participate in the synthesis of methyl anisate and ethyl anisate, which are important raw materials for the preparation of flavors, toothpastes and dentifrice. However, there are few reports on the use of fengzhisu as a pesticide ingredient. Our laboratory previously discovered that fengzhisu can be isolated from the metabolites of endophytic fungi in ice flowers, and experiments have proved that fengzhisu has plant growth-promoting properties. Therefore, if fengzhisu from microbial sources can be used as an active ingredient of pesticides and prepared into pesticide compositions with existing pesticides, it will be expected to solve the problem that common pesticides usually have a single activity and poor technical effects in preventing and controlling pests and diseases and increasing crop yields.

The method of investigating the effectiveness of the prevention of the new black ground spider scale is to count the diseased plants of peanuts infected with the new black ground spider scale at the roots.

[0094] Grading of the severity of cutworm disease: the number of cutworms per unit volume of soil surveyed is 0 = 0; the number of cutworms per unit volume of soil surveyed is 1-6 = 1; the number of cutworms per unit volume of soil surveyed is 7-12 = 2; the number of cutworms per unit volume of soil surveyed is 13-18 = 3; the number of cutworms per unit volume of soil surveyed is 19-24 = 4; the number of cutworms per unit volume of soil surveyed is greater than 25 = 5.

[0095] The severity of the disease of the new black spider scale is graded as follows: no larvae parasitizing on the roots = 0; a small number of larvae on the roots, yellowing of the leaf edges, and slightly weakened root system = 1; a large amount of yellowing of the leaves, slightly weakened root system, and reduced lateral roots = 2; yellowing and falling of leaves, obvious weakening of the root system, and a large reduction in lateral roots = 3; slow plant growth and root rot = 4; the entire plant withers and dies, and the root system rots = 5.

[0096] Grading of the degree of grub disease: the number of grubs in the unit volume of soil surveyed is 0 = 0; the number of grubs in the unit volume of soil surveyed is 1-4 = 1; the number of grubs in the unit volume of soil surveyed is 5-8 = 2; the number of grubs in the unit volume of soil surveyed is 9-12 = 3; the number of grubs in the unit volume of soil surveyed is 13-16 = 4; the number of grubs in the unit volume of soil surveyed is greater than 17 = 5.

[0097] The disease index and prevention effect calculation formula are the same as in Example 1.
