西维因为氨基钾酸酯类杀虫剂,对500多种农业及卫生害虫有效。具有广谱、低毒、使用安全的特点。 西维因胶悬剂为近年来发展的一种新剂型。特点在于以水做基质,再经水稀释后乳化快、悬浮性好、喷雾施用方便、有提高药效、延长残效等优点。并增加耐雨水冲刷能力。和对天敌的安全性。因而使用方便并减少对环境的污染。 在1982—83年对西维因胶悬剂进行配方生物筛选,室内做了杀虫毒力及耐雨淋试验,并与西维因可湿粉对比,进行了田间应用试验。
Xviiv is effective for more than 500 agricultural and hygienic pests because of its use as a carbamate insecticide. Has a broad spectrum, low toxicity, the use of safe features. Cimetidine suspension for the development of a new dosage form in recent years. Characterized by the water as a matrix, and then diluted with water after emulsification, suspension, spray easy to use, to improve efficacy, to extend the residual and so on. And increase resistance to rain erosion. And the safety of natural enemies. Thus easy to use and reduce environmental pollution. In 1982-83, we carried out the formula biological screening of the West Vinyl Encapsulant. The pesticides were tested for insecticidal virulence and rain resistance indoors, and compared with the West Viability WP.
