Embodiment 1

[0044]Raw materials: Boluohui extract (containing sanguinarine sulfate), tobacco extract (containing nicotine sulfate), tea oil cake extract (containing tea saponin), borneol camphor extract (containing natural borneol), Azone, sodium dodecylbenzenesulfonate, sodium lignosulfonate, anhydrous sodium sulfate; prepared as soluble powder. The labeled content of sanguinarine in the soluble powder is 1%, the labeled content of nicotine is 5%, the labeled content of tea saponin is 5%, and the labeled content of natural borneol is 0.2%. When the prepared powder is diluted 600 times, the control effect of indoor cabbage caterpillar bioassay test can reach more than 90%. The prepared insecticide is diluted 600-800 times, and sprayed in the field to prevent and control cabbage caterpillars. Three days later, the survey shows that the control rate of cabbage cabbage caterpillars reaches more than 91%.

Embodiment 2

[0046] Raw materials: Boluohui extract (contains sanguinarine hydrochloride), tobacco extract (contains nicotine hydrochloride), tea oil cake extract (contains tea saponin), borneol camphor extract (contains natural borneol ), azone, sodium dodecylbenzenesulfonate, and sodium lignosulfonate; the above raw materials were dissolved in purified water and stirred thoroughly for 30 minutes to prepare the water preparation with a marked content of 1% sanguinarine and a marked content of nicotine The labeled content of tea saponin is 10%, and the labeled content of natural borneol is 0.1%. When the prepared water preparation is diluted 1000 times, the control effect of the indoor aphid killing bioassay test can reach more than 95%. The prepared insecticide is diluted 1000-1200 times, sprayed in the field to prevent and control aphids, and the aphids control rate reaches more than 95% after three days of investigation.

Embodiment 3

[0048] Raw materials: Boluohui extract (contains sanguinarine hydrochloride), tobacco extract (contains nicotine hydrochloride), tea oil cake extract (contains tea saponin), borneol camphor extract (contains natural borneol ), azone, sodium dodecylbenzenesulfonate, and sodium lignosulfonate; the above raw materials were dissolved in purified water and stirred for 30 minutes to prepare a water solution with a marked content of 0.5% sanguinarine and a marked content of nicotine 10%, the labeled content of tea saponin is 5%, and the labeled content of natural borneol is 0.5%. When the prepared water preparation is diluted 1000 times, the control effect of the indoor rice planthopper bioassay test can reach more than 93%. The prepared insecticide is diluted 1000-1200 times and sprayed in the field to prevent and control rice planthoppers. Three days later, the control rate of rice planthoppers reaches more than 85%.

Abstract

The invention discloses a phyto-pesticide and a use method thereof. The pesticide is used for controlling aphids, rice planthoppers and cabbage worms. A principle of 'monarch, minister, adjuvant and messenger' for drug formula in philosophy of the traditional Chinese medicament is used in the development of a product of the phyto-pesticide formula. The phyto-pesticide comprises four plant extracts including 0.5 to 10 percent by sanguinarine of macleaya cordata, which plays a main insect killing role and serves as a monarch drug; 2 to 20 percent by nicotinamide of tobacco extract, which is used for improving the insect killing effect of the 'monarch drug' and serves as a 'minister drug'; 5 to 10 percent by teasaponin of tea oil cake, which is used for making a target insect refuse to have food, generates certain gastrointestinal toxicity to reduce the viability of the insect and serves as an 'adjuvant drug'; 0.1 to 0.5 percent by natural borneol(L(-)-Borneol ) of borneol camphor, which can expel the insect and serves as a 'messenger drug'. The formula combines the 'monarch, minister, adjuvant and messenger' composite formula and an additive and a carrier to prepare the pesticide with insect expelling effect. The phyto-pesticide is effective, free from residue and environmentally-friendly.

Description

technical field [0001] The invention relates to an insecticide formula and its application method, in particular to a pure botanical pesticide insecticide formula and its application. Background technique [0002] With the development of human society, people have higher and higher requirements for environmental protection and food safety. "Green agriculture" and "organic agriculture" have become the direction of agricultural development. With the intensification of human activities, the deterioration of the environment has become more serious, and the damage by diseases and insect pests has become more frequent. To effectively control the growth of plant pathogenic bacteria and the harm of pests, to minimize pesticide residues, and to provide people with pollution-free agricultural products has always been the pursuit of research in the field of pesticides. Using natural plants as raw materials to manufacture botanical fungicides has become one of the effective ways to ach...
