Abstract

The invention discloses a vegetable insecticide and a preparing method thereof. The vegetable insecticide is prepared from, by weight, 1-2 parts of hairyvein agrimony, 3-6 parts of aloe, 2-3 parts of fructus ulmi, 10-15 parts of marigold, 3-7 parts of mint, 6-10 parts of radix sophorae flavescentis, 3-4 parts of aconitine, 7-11 parts of pericarpium granati, 8-12 parts of tea saponin, 5.6-8.7 parts of emulsifying agent, 3-5 parts of penetrant and 4-7 parts of stabilizer. Through the synergistic effect of all the raw materials, the contact killing capacity and insect repelling capacity of the insecticide can be improved; by adding hairyvein agrimony, aloe, fructus ulmi, radix sophorae flavescentis and aconitine, the insecticide has the contact killing capacity for various types of harmful insects; by adding marigold and pericarpium granati, the insecticide has the repelling capacity for various types of harmful insects; thus, the vegetable insecticide is good in insect killing effect and can be widely used for controlling fruit and vegetable harmful insects such as cabbage caterpillar, aphid, armyworm, green fruitworm, oriental tobacco budworm, cotton bollworm, leaf folder and pear psylla, the control effect of the insecticide reaches 89-98%, and harmful insects can not have drug resistance.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a plant pesticide and a preparation method thereof. Background technique [0002] my country is a country with a large population and a shortage of arable land. Increasing grain production and farmers' income has always been the main goal of agricultural production. However, for agricultural production, the loss caused by crop diseases, insect pests and weeds can reach up to 70%, and 40% of the loss can be recovered through the correct use of pesticides. It can be seen that the use of pesticides to control diseases, insect pests and weeds is a necessary technical measure to reduce the production of agricultural products. As we all know, chemical pesticides have a good control effect on plant diseases and insect pests, but the environmental pollution caused by chemical pesticides and the harm to ecological balance are unavoidable facts for human beings. In contrast, botanical pesticide...
