Embodiment 1

[0034] Rice borer repellent microemulsion, the components are 20% cedarol, 0.7% ocimene, 1.5% α-pinene, 2.8% methyl cinnamate, 0.5% 2,6-di-tert-butyl-p-cresol, dodecane Sodium phenylmethanesulfonate 2%, glycerin 4.5%, sodium benzoate 0.3%, gull gum 0.35%, emulsifier 12%, and the balance is water.

[0035] The preparation steps are as follows:

[0036] (1) Mix and stir the active ingredients (cypressene, ocimene, α-pinene, methyl cinnamate), heat and dissolve to obtain the oil phase;

[0037] (2) Mix water and all additives evenly;

[0038] (3) Slowly add (1) into (2), stir, shear and emulsify, take samples, test, and the product is ready.

Embodiment 2

[0040] Rice borer repellent microemulsion, the components are 12% cedarene, 1.2% ocimene, 3.1% α-pinene, 4.8% methyl cinnamate, 0.03% sodium ascorbate, 2.5% sodium dodecylbenzene methanesulfonate, Glycerin 4.0%, sodium benzoate 0.4%, gull gum 0.5%, emulsifier 10%, and the balance is water.

[0041] The preparation method is the same as in Example 1.

Embodiment 3

[0043] Rice borer repellent microemulsion, the components are 5.3% cedarene, 6.2% ocimene, 0.5% α-pinene, 22.5% methyl cinnamate, 0.05% sodium ascorbate; 3% sodium dodecylbenzenemethanesulfonate, Glycerin 5%, sodium benzoate 0.3%, gull gum 0.5%, emulsifier 12%, and the balance is water.

[0044] The preparation method is the same as in Example 1.

Abstract

The invention discloses a rice stem borer repellent, a preparation method and application thereof. The repellent comprises the following components by weight: 10-30% of cedrol, 0.5-10% of ocimene, 0.3-10% of alpha-pinene, 2-8% of methyl cinnamate, and the balance water and an assistant. With sustained release substances having special smell, the repellent provided by the invention can generate a repelling effect on adult female oviposition of rice stem borers (Chilo suppressalis and Sesamia inferens), thereby reducing the damage and population number of rice stem borers. With the characteristics of low cost, high efficiency, environmental friendliness, safety to animals and human, etc., the rice stem borer repellent provided by the invention has broad industrialization prospects and simple preparation method, is especially suitable for use in pollution-free production of rice, and has broad economic, social and ecological benefits.

Description

technical field [0001] The invention relates to an insect repellent, in particular to a repellent for rice borer adults, the main pest of rice, and a preparation method thereof. Background technique [0002] Rice borers, including Chiloborer Chilo suppressalis and large borer Sesamia inferens , is an important pest of rice in my country. Chilo borer belongs to Pyralidae of Lepidoptera and belongs to Noctuidae of Lepidoptera. It is widely distributed in temperate and subtropical Asia. The host plants include rice, corn, sugarcane, millet, broad bean, wild rice stem, sorghum, wheat, etc. . In recent years, with changes in my country's farming system and rice varieties, and climate warming, the living environment of Chilo borer has been greatly improved, and the population has increased significantly. Rice stem borer, mainly rice stem borer, has become another major pest that seriously threatens the national economy and people's livelihood after the rice planthopper in th...
