一、要重视农药的混用问题,混合剂型必须有足够的试验数据做依据,使其正常发展。 据国内外资料:一些农药通过混用可以增效,达到兼治,或者混合以后对农药的物理性状有所改进,有时可以提高稳定性。目前在农药混合制剂的研究、生产上有些问题值得注意、有的混合制剂缺少必要的毒性试验数据,有的药效试验数据不够充分,有的已大量出售、使用,但尚未制订产品的技术标准,缺少科学的分析方法等。这样的农药混合制剂生产、销售后会造成新的农药质量问题。
First, we should pay attention to the mixing of pesticides, mixed dosage forms must have enough test data to make basis for its normal development. According to the data both at home and abroad, some pesticides can be synergized through mixing to achieve both cure and cure, or improve the physical properties of pesticides after mixing, sometimes improving the stability. At present, some problems in the research and production of pesticide mixed preparations are noteworthy. Some mixed preparations lack the necessary toxicity test data, and some of the efficacy test data are not sufficient enough. Some have been sold and used in large quantities, but the technical standards of the products have not yet been formulated , The lack of scientific analysis methods. The production and sale of such pesticide mixes will result in new pesticide quality problems.
