表面活性剂、喷液量及杂草叶角对普杀特在非敏感杂草马唐叶片上的喷后附着量有明显的独立影响和交互影响,其中表面活性剂的影响最大。供试的6种非离子型表面活性剂均因显著降低了普杀特药液的表面张力从而显著提高了其在马唐叶片上的喷后附着量,其中ScOil和Silwet—L77对其提高幅度最大;普杀特在马唐叶片上的喷后附着量随着喷液量的减少逐步增加,但在0—90°范围内随着马唐叶角的减小而减少,其由于喷液量的增大或马唐叶角的减小而引起的下降量,可通过加入非离子型表面活性剂而得到补偿,加入非离子型表面活性剂配合下午微液量(90L/ha)喷施,可望最大限度地增加普杀特在其非敏感杂草叶片上的喷后附着量,进而提高其药效,降低其使用成本和减少其在土壤中的残留。
Surfactant, spray volume and weed angle had significant independent and interactive effects on Pseudosteloxins’ spraying weight on non-sensitive weedy crabgrass leaves, among which surfactants were the most influential. Six kinds of nonionic surfactants tested significantly reduced the surface tension of Propoxur solution and significantly increased the spray adhesion of Cinnamomum caeruleus leaves. ScOil and Silwet-L77 increased the surface tension Maximum; Putex special spray on the leaves of Crab Tang spray volume with the decrease of the amount of spray increased gradually, but in the range of 0-90 ° with the decrease of the angle of the cantactant, which due to the amount of spray Or the decrease of the angle of the horse’s tangle can be compensated by adding the non-ionic surfactant, adding the non-ionic surfactant and spraying the afternoon micro-liquid (90L / ha) It is expected to maximize the amount of Psoxrate sprayed on its insensitive weed leaves, thereby increasing its efficacy, reducing its cost of use and reducing its residuals in the soil.
