摘 要:甲硫嘧磺。▽(shí)驗代號HNPC-C9908)是湖南化工研究院自主研制的新型磺酰脲類(lèi)除草劑,主要用于小麥田雜草防除。為了提高它的除草效果、拓寬除草譜、改善對作物的安全性,將甲硫嘧磺隆與撲草凈以1 ∶ 5(m/m)混用制成水分散粒劑。經(jīng)過(guò)助劑篩選,得出了其水分散粒劑的優(yōu)惠配方為(m/m):甲硫嘧磺-12.0%、撲草凈-60.0%、分散劑A10-10.0%、潤濕劑B6-5.0%、崩解劑C4-2.0%、粘結劑D1-1.0%、載體補至100%。按上述配方配制的72%甲硫嘧磺隆·撲草凈水分散粒劑,各項技術(shù)指標和熱貯穩定性測定均達到有關(guān)水分散粒劑的質(zhì)量標準。 |

Abstract:HNPC-C9908 is a new sulfonylurea herbicide researched and developed by Hunan Research Institute of Chemical Industry,and mainly used to control weeds in the wheat field. To enhance the efficacy of controlling weeds,broadening the weed spectra and improving the safety to crops,mixture water dispersible granule(WDG)formulation of HNPC-C9908 and prometryne1∶5(m/m) was investigated in the paper. The optimum compositions for 75%WDG obtained by a series of adjuvant screening test were as follows(m/m):HNPC-C9908 12.0%,prometryne 60%,dispersant A10 10.0%,wetting agent B6 5.0%,collapsing agent C4 2.0%,adhesive agent D1 1.0% and carrier filled up to 100%. The parameters of 75% WDG such as technical index and heat-storage stability meeted the Chinese quality standard of the formulation product. |
