experiment example 1

[0051] Experimental example 1 Indoor virulence determination of control tomato virus

[0052] Pathogen tested: tomato virus disease

[0053] Test method: live potting method was adopted, each treatment was performed 10 times, and after 7 days, the disease index was classified and investigated, and the EC50 co-toxicity coefficient was calculated. The test results are shown in Table 1. In the test results: co-toxicity coefficient (CTC) ≥ 120 means synergistic effect; 80 < CTC < means additive effect; CTC ≤ 80 means antagonistic effect.

[0054] Table 1 Toxicity determination of sanguinarine, amino oligosaccharins and their mixtures against tomato virus diseases

[0055]

[0056] As can be seen from the results in Table 1, the test results of different ratios show that the dilution of sanguinarine and amino oligosaccharin aqueous preparations in effective proportions shows a strong synergistic effect, wherein sanguinarine: amino oligosaccharin The synergistic effect is obvio...

Embodiment 1

[0058] Example 1: 5% sanguinarine · oligosaccharin aqueous solution

[0059] 0.5g of sanguinarine, 4.5g of amino oligosaccharin, 10g of methanol, 6g of castor oil, 15g of butanoic acid, 5g of ethylene glycol, 8g of ascorbic acid, and 100g of deionized water;

Embodiment 2

[0060] Example 2: 8% sanguinarine · oligosaccharin water

[0061] 2g sanguinarine, 6g amino oligosaccharin, 10g cyclohexanone, 8g tristyrylphenol polyoxyethylene ether phosphate, 10g synergistic amine, 5g propylene glycol, 8% carboxymethylcellulose, deionized water to make up 100g ;

Abstract

The invention relates to the technical field of pesticide, in particular to a pesticide composition containing sanguinarine (macleaya alkaloids). The pesticide composition is prepared from, by weight, 0.1-30% of first pesticide, 0.1-80% of second pesticide, 5-80% of auxiliaries and 14.9-94.8% of a solvent or filler. The first pesticide is sanguinarine. The second pesticide comprises one of amino-oligosaccharin, cnidium lactone, spinosad, santonin, azadirachtin, wilforgine, neochamaejasmin, hyoscyamine and matrine. The auxiliaries comprise one or more of surfactant, a synergistic agent, an emulsifier, an anti-freezing agent, a dispersing agent, a wetting agent, a thickening agent, an ultraviolet protecting agent, a defoaming agent and an adhering agent. The pesticide belongs to plant source compound pesticide, the compound synergistic effect is remarkable, the pesticide composition can be used for preventing and treating various plant diseases, and pollution of chemical pesticide to the environment is reduced.

Description

technical field [0001] The present invention relates to the technical field of pesticides, in particular to a pesticide composition containing sanguinarine (Pulotina alkaloid) and a preparation method thereof. Background technique [0002] For thousands of years, people have used various methods to protect their crops from diseases, insects and other harmful organisms, among which the use of pesticides is one of the most effective methods. Most of the early pesticides came from plants. After the 1940s, chemically synthesized pesticides became popular due to their high efficiency, quick effect, and wide insecticidal spectrum, which caused the research and use of botanical pesticides to fall into a slump. [0003] In recent years, with the rapid development of national economy, people pay more and more attention to the sustainable development of agricultural production and the coordinated development of human and environment. In the traditional production of fruits and veget...
