异菌脲

由于甲基托布津、异菌脲和多菌灵对MT-06抑制率强，不宜混配，遂将这3种农药排除。

Results showed that thiophanate methyl , iprodione and carbendazim had strong inhibitory effect on MT-06 , so these three kinds of fungicides were abandoned .

在多氧霉素B存在下分离的抗多氧霉素B变异体对异菌脲的敏感性通常大于其母本菌株。

Under the existence of polyoxin B , the isolated polyoxin B resistant mutants were generally more sensitive to iprodione than their wild isolates .

/hm2处理剂量下，施药3～4次，间隔7d处理对番茄灰霉病有较好的防效，其防效优于50%异菌脲WP750ga。

/ ha in field trail after 3 to 4 times treatment at intervals 7 d , and its control effects were much higher than iprodione 750 g a.

基质分散固相萃取-高效液相色谱法测定水果中的异菌脲残留量

Combination of Matrix Solid Phase Dispersion Extraction with High Performance Liquid Chromatography for the Determination of Iprodione Residue in Fruits

试验结果表明，异菌脲的含量与峰面积之间呈线性关系。异菌脲的最小检出量为0.005ng。

The results showed that the linear relationship between peak area and iprodione content was good and the minimum detectable amount was 0.005 ng .

结果如下：1.建立了异菌脲在梨和土壤中气相色谱分析方法。

The results are as follows : 1 . The analytical method of iprodione residue in pear and soil was established with gas chromatography .

异菌脲为广谱性、接触、低毒杂环类杀菌剂，在梨生产中普遍使用，对梨黑星病具有较好的防治效果。

Iprodione is a broad-spectrum , low toxicity , heterocyclic fungicide . It is commonly used in the pear production , and has obvious effect to control scab of pear .

说明该残留分析方法的灵敏度、准确度、精密度等均符合农药残留检测的要求。2.农药消解动态：采用田间试验方法，研究了10%异菌脲乳油在梨和土壤中残留消解动态规律。

The sensitivity , accuracy and precision of this method are consistent with requirements of pesticide residue testing . 2 . Degradations experiments of iprodione in pear and soil were achieved in two pieces of field in Gaocheng and Handan city .
