Problems solved by technology

[0007] At present, there are very few medicaments used to prevent and control tobacco root-knot nematode in China, and they are highly toxic pesticides. Due to long-term use, drug resistance has been produced. Therefore, it is imperative to find a new medicament for preventing and treating tobacco root-knot nematode.

[0057] Example 225% Abamectin Carbosulfan Emulsion Indoor Formula Screening Report

[0058] In order to clarify the prevention and control effects of abamectin and carbosulfan and their mixtures in different proportions on tobacco root-knot nematode disease, we compounded commercially available abamectin and carbosulfan, The abamectin·carbsulfur water emulsion was made, and it was found that it had obvious synergistic effect. After indoor formula screening, the best ratio was selected to be abamectin: carbosulfan 0.5: 24.5, with a synergistic coefficient of 192, which is extremely significant. The test situation is reported as follows:

Abstract

The invention provides an anti-tobacco nematodosis drug composition of abamectin and carbosulfan, comprising abamectin, carbosulfan, solvent, emulsifier and water, wherein, the ratio between abamectinand carbosulfan is 1:1-60, and the optimal proportion is 1:49; the dosage form is emulsion in water; the solvent is ethylene glycol; the emulsifier is calcium dodecylbenzene sulfonate and triphenylethyl phenol polyoxyethylene ether; and water is deionized water. The anti-tobacco nematodosis drug composition of abamectin and carbosulfan of the invention is used for preventing and treatinsg tobaccorot knot nematodosis and is characterized by high efficiency, low toxicity and no pollution to the environment.

Description

technical field [0001] The invention relates to a pesticide, in particular a combination of avermectin and carbosulfan anti-tobacco nematode disease medicine is designed. Background technique [0002] Nematodes are a huge biological group in nature. According to Hyman's (1950) estimate, there are more than 500,000 species in the world, among which plant parasitic nematodes are a large class of pathogens with economic importance and have become one of the important factors restricting agricultural production. According to the statistics of P.P.Esser, as of 1990, 207 genera and 4832 species of plant parasitic nematodes have been reported all over the world. According to the latest statistics of the United States in 1994, the annual loss of food and fiber crops caused by plant parasitic nematodes is about 12%, and the United States alone has reached 8 billion US dollars, while the world has reached 78 billion US dollars. [0003] Plant-parasitic nematodes mainly parasitize on...
