生物除草剂剂型研究进展

生物除草剂由于受到生物因素、环境因素和技术因素的影响,使其开发受到一定限制。生物除草剂固体剂型与液体剂型在一定程度上克服了对湿度的依赖性,使其保证了生物活性,使用时在目标植物上能保持湿润,在田间适宜条件下发挥其优良效果;由于若干新型添加剂和先进技术的应用,使其液体剂型得到进一步开发。本文介绍了生物除草剂一些新的固体和液体剂型的研究进展。

Advances in bioherbicide formulation

Reducing dew dependence is a principal aim in the formulation of many potential bioherbicides. In the present paper, the research attempting in part to overcome this problem via the development of novel solid and liquid formulations is described. Typically solid formulations must be able to survive the field conditions and remain inactivated until suitable conditions appear. Liquid formulations have the potential to function soon after application provided they remain moist on the target plant surface. Several attempts to improve water-holding capacity in liquid formulations have been examined. The use of multiple emulsions of water in oil has recently shown promise.
