6％密达颗粒不同剂型防治蔬菜地蜗牛田间对比试验研究

6％密达颗粒剂是一种杀螺剂，广泛用于蔬菜、棉花、水稻、烟草等作物上。通过对6％密达杀螺颗粒剂不同剂型防治蔬菜地蜗牛的田间对比试验，结果表明：在施药后，6％密达颗粒剂小颗粒型在不同时期优于耐水型、略高于原剂型的防治效果，被雨水冲刷后不易变形，并有一定的持效性和引诱能力；在整个实验过程中未发现该药剂对蔬菜有危害现象。因此，在使用6％原密达颗粒剂的基础上，可以进一步引用小颗粒型，提高防虫效果。

6% Meter Pellet Different Dosage-Form Preventing and Controlling Vegetables Snail Field Contrast Experiment

6% meter granular formulation are one kind of molluscicide, widely uses in crops and so in vegetables, cotton, paddy rice, tobacco. Through kills the spiral granular formulation different dosage -form preventing and controlling vegetables snail to 6% meter the field contrast experiment, finally indicated：After pesticiding application, 6% meter granular formulation finely ground particles surpass water resistant in the different time, are higher than the original dosage - form slightly the preven- ting and controlling effect, after is not been easy by rain wash to distort, and has certain holds the effect and tempts the ability; And has not discovered this medicament in the entire experimental process to the vegetables promising evil phenomenon. There- fore, in uses 6% original meter granular formulation in the foundation, may further quote the finely ground particles, enhances the insect proof effect.
