摘要
对10%乳油在棉花及土壤中残留动态进行了测定,结果表明,10%歼灭乳油在棉花植株中半衰期为3~4d,16~18d可降解对结到95%以上;在土壤中半衰期为8~14d,经过37~60d可降解到95%以上。棉籽中未检出歼灭残留,低于FAO/WHO规定的最高残留限量。
AGC method was carried out to examine residual dynamics of 10% beta-cypermethrin EC in cotton and soil. The results showed that the half-lives of 10% beta-cypermethrin EC in cotton and soils were 3~4 d and 8~14 d respectively; beta-cypermethrin EC degraded above 95% after 16~18 d in cotton and after 37~60 d in soil. The pesticide residues were not found in cotton seeds, which is much lower than MRL of FAO and WHO.
