斜纹夜蛾杀虫剂田间药效试验报告

本文对斜纹夜蛾核多角体病毒（Spodoptera litura nucleopolyhedrovirus,SpliNPV）郴州株及农药市场上的五种杀虫剂进行田间药效试验,结果表明,以好乐士25g/升乳油为最好,其平均相对防效为100.0%,所有药剂的相对防效都与对照药剂无显著差异,但防效都略好于阿维菌素乳油,生物杀虫剂的防效总体都表现较好,尤其是郴州株斜纹夜蛾核多角体病毒＋增效剂的防效比较理想,药后第8天防效达84.8%,它是最安全的生物药剂,值得推广应用。

Novel layered pesticide slow/controlled release materials——supramolecular structure and slow release property of glyphosate intercalated layered double hydroxides

Two different interlayer structured glyphosate(GLY) intercalated MgAI layered double hydroxides, as novel pesticide slow/controlled release materials, have been synthesized by co-precipitation method under various reaction pH values. The slow/controlled release properties have been tested in Na2CO3 aqueous solution. The release mechanism has been interpreted on the basis of the ion-exchange between the guest GLY anions in the lamellar host and CO3^2- in the release media, and the diffusion process of GLY anions in the interstice and interlayer of GLY intercalates, i.e.diffusion through the particles, is the rate-limiting step of GLY release process. The GLY intercalate assembled at lower pH, possessing higher interlayer gallery height and vertical monolayered arrangement of guest anions in the interlayer with larger packing density, exhibits better slow release property than that assembled at higher pH. The results reveal that the layered double hydroxides have potential application in the pesticide slow/controlled release area.     

Research on the rheological properties of pesticide suspension concentrate

This study reports research on pesticide suspension rheology and a new rheologicaI parameter, the relative value of approach, which has great advantage for judging the physical stability of a pesticide suspension concentrate. Experiments showed that the system can form stable dispersions when the value of the relative value of approach (St) is less than 0.1.     

水溶性气雾杀虫剂的研制
