Embodiment 1

[0022] The present embodiment prepares biological (plant) insecticide according to the following steps:

[0023] (1) Take 30 parts of wormwood stems and leaves, 69 parts of Lycium chinensis stems and leaves and add 1 part of water to fully grind.

[0024] (2) Filter the ground material obtained in step (1) with a funnel and take its juice to obtain a biological (plant) insecticide and insect repellent.

[0025] (3) The prepared insecticide repellent and water are diluted 1:500 times, and then sprayed on the leaves and stems of fruits and vegetables with a sprayer.

[0026] After 24 hours of spraying, it was tested that the adult beet armyworm, cabbage caterpillar, and cotton bollworm had a mortality rate of 89.62%, and the rest were driven away; The pests are also expelled after smelling the smell, and the fruits and vegetables will not be harmed.

Embodiment 2

[0028] (1) Take 68 parts of wormwood stems and leaves, 30 parts of Lycium chinensis stems and leaves and add 2 parts of water to fully grind.

[0029] (2) Filter the ground material obtained in step (1) with a funnel and take its juice to obtain a biological (plant) insecticide and insect repellent.

[0030] (3) The prepared insecticide repellent and water are diluted 1:500 times, and then sprayed on the leaves and stems of fruits and vegetables with a sprayer.

[0031] After 24 hours of spraying, it was tested that the adult beet armyworm, cabbage caterpillar and cotton bollworm had a mortality rate of 86.16%, and most of the rest were driven away; the beet armyworm, cabbage caterpillar and cotton bollworm larvae had a mortality rate of 91.11%. , the undead pests are also expelled after smelling the smell, and will not harm the fruits and vegetables.

Abstract

The invention discloses a green biological (plant) Gowen vine stem leaf and wormwood stem leaf insecticidal insect repellant formula and a preparation method thereof. The green biological (plant) Gowen vine stem leaf and wormwood stem leaf insecticidal insect repellant formula is characterized in that peculiar components and taste of wormwood stem leaves in the insecticidal insect repellant are utilized, so that pests are repelled; and the stomach toxicity effect of juice of the Gowen vine stem leaves in the insecticidal insect repellant is utilized, so that the pests are killed. After the insecticidal insect repellant and water are properly diluted, the diluent is sprayed on the biological (plant) leaves and stems, the peculiar wormwood odor and Gowen vine stem leaves in the repellant have repelling and stomach killing activity on various pests, the insecticidal insect repellant can be widely applied to prevention and control of various fruit and vegetable pests, and fruits and vegetables are effectively protected. The materials are natural and are non-toxic on human and livestock, and new support is provided for biological (plant) prevention and control of the pests.

Description

technical field [0001] The invention relates to a natural non-toxic biological (plant) insecticide and repellent formulation and a preparation method thereof, in particular to an insecticide and repellent using the stems and leaves of Lycidium citrifolia as raw materials and a preparation method thereof. technical background [0002] Pests can reduce the yield and quality of fruits and vegetables, spread diseases and insect pests, and do great harm to fruits and vegetables. Although chemical insecticides can solve the problem of pest control, repeated and extensive use of chemical insecticides has caused problems of increased resistance of pests, environmental pollution, and pesticide residues in agricultural products. In order to avoid the above problems, people have found through research that some biological (plant) components have the activity of repelling and killing insects in the stomach, and can be widely used in the prevention and control of various fruit and vegeta...
