氯虫苯甲酰胺具有较好的内吸性,并能沿木质部向上输导,保护新生茎叶和花序,持效期长达1个月左右。该药对玉米的安全性好,在玉米喇叭口期加足水量将药喷淋到玉米茎顶,药物能被新生茎叶吸收,并向上传导,能在较长时间内保护新生茎叶和玉米穗。氯虫苯甲酰胺不能沿韧皮部传导,仅将药喷到外围展开叶上,药物被叶片吸收后不能向下输送到茎部,因而不能沿茎部木质部向新生茎叶和玉米穗输送,因而 Chlordimeform benzamide has good internal absorption, and can guide upwards along the xylem to protect new stems and leaves and inflorescences, persist for up to 1 month. The medicine is safe to corn, add enough water in the corn trumpet mouth to sprinkle the medicine to the top of the corn stem, the drug can be absorbed by new stems and leaves and upwards, and can protect newborn stems, leaves and corn for a long time ear. Chlorantraniliproxen can not be transmitted along the phloem, only the drug is sprayed onto the outer expanded leaf. After being absorbed by the leaf, the drug can not be transported down to the stem and can not be transported to the new stem and leaf and the corn ear along the stem xylem
