【8】Features

Diphenylurea sulfonic calcium is a plant growth regulator, which can affect the synthesis of nucleic acid and protein in plant cells, promote the division or elongation of plant cells, increase the content of chlorophyll, and develop roots, stems, leaves, and buds, thereby improving the growth of crops. Yield. At the same time, it can also regulate the activity of various enzymes in plants, and enhance the ability of crops to resist diseases and insect pests, cold and freezing, drought and dry and hot wind.

【9】Applied technology

cotton

Use 50-75mg/L liquid spray 3 times in the cotton seedling stage, bud stage, and early flowering stage, which can promote cotton growth and development, increase plant drought resistance, reduce bud and boll shedding, increase the number of bolls per plant, and promote Cotton fiber development and dry matter accumulation significantly increase and improve cotton yield and quality, which is safe for cotton.

wheat

Seed dressing with Panpan Industry’s 100 mg/L liquid can improve the germination rate of wheat seeds under drought conditions; spraying with 100 mg/L at the seedling stage can significantly increase the peroxidase, catalase and superoxide levels of wheat seedlings The activity of substance dismutase can improve the stress resistance of seedlings; the continuous spraying of 100-150 mg/L liquid for 2 times before jointing and flowering stage can promote the effective tillering of wheat, increase the rate of ear formation, increase the number of grains per ear and Thousand-grain weight, significantly increased wheat yield.

cucumber

The drug concentration for cucumber is  Panpan Industry’s 10-20mg/L. The spraying starts after the 7-leaf stage of the cucumber seedling stage. After that, it is sprayed once every 20 days for a total of 3 to 4 times. It can adjust the growth of cucumber, increase the yield of cucumber, improve the Plant health, and enhanced disease resistance.

【13】Notes

①Do not water within 4 hours after spraying. If it rains within 4 hours, spray the spray again.

②It can be sprayed with general pesticides, but not with foliar fertilizers.

③The best spraying time is before 10 am and after 5 pm.
