When it comes to paclobutrazol, many farmers have heard it. Paclobutrazol is a commonly used plant growth regulator. It has the function of controlling the shoots and increasing the resistance to stress. It can significantly increase crop yield. Paclobutrazol can be used on a variety of crops. Let us come to understand it. First, control growth, lodging resistance Corn: soaking seeds should be shallow sowing, soaking for 10~12 hours before sowing, adding 1kg of seed and adding 1.5g of 15% paclobutrazol wet powder and adding 100g of water, stirring once every 3~4 hours. Wheat: Sprayed 40g of 15% paclobutrazol wet powder to 50kg per 667m2 in the first stage of the wheat seedling, from the wheat to the jointing. Rapeseed: In order to cultivate short-legged and strong seedlings, the seedling bed has high level of fertilizer and water, sowing early, and the seedling bed with high density is 3~4 leaf stage, and 40g of 15% paclobutrazol can be sprayed with 50kg of water per 667m2. Peanut: 50g of 15% paclobutrazol WP can be sprayed with 50kg of water per 667m2 during full bloom. Cotton: In the medium term, 50g of 15% paclobutrazol wet powder is sprayed with 50kg of water per 667m2. Rice: In order to cultivate the strong cockroaches to prevent lodging, the age of cockroaches is about 35 days. In the single season, the middle and late rice fields are sprayed with 175-200g of 15% paclobutrazol WP of 100kg per 667m2 for 25 days before transplanting. The high-yield field is partially prosperous and high-stalked and easy to fall. It is sprayed with 175-200g of 15% paclobutrazol wettable powder and 100kg of water per 667m2 30-40 days before heading. Soybean: 60g of 15% paclobutrazol wet powder and 50kg of water per 667m2 of flowering. Potato: When the plant height is 25-30 cm, 60 g of 15% paclobutrazol wet powder is sprayed with 50 kg of water per 667 m2. Watermelon: When planting seedlings, spray 50~100mg/L liquid on the cotyledon of watermelon or in the vine to 60cm. It can be used to grow the plant. Zucchini: After 3~4 true leaves are unfolded, spraying with 4~20mg/L liquid can shorten the internodes, thicken the leaves, increase cold resistance and disease resistance. Pepper: Spray at 10~20mg/L liquid when the seedling is 6~7cm. Eggplant: When 5~6 true leaves are used, 10~20mg/L pesticide liquid is used for foliar spraying, which can make eggplant strong seedlings. Second, control Apple: In the autumn branch, each plant is sprayed with 15~20915% paclobutrazol wettable powder, or the new shoot is 5-10cm long, sprayed with 15% paclobutrazol wettable powder 500-700 times water for 10 days, for a total of 3 times. . Pear: The new shoot is 5~10cm long and sprayed with 15% paclobutrazol wet powder 500~700 times water for 10 days, three times. Peach: Hawthorn: Under the autumn or spring branch, each plant 10~15g is applied with 15% paclobutrazol. Citrus: 15% paclobutrazol wet powder 150 times with water foliar spray at the end of summer. Cherry: Each plant uses 15% paclobutrazol wet powder 4~6g soil. Mango: In early May, 15~20g of 15% paclobutrazol can be mixed with 15-20kg of water per plant, and the ring groove is applied. Tobacco: 60g of 15% paclobutrazol WP can be sprayed with 50kg of water per 667m2 in the 5~7 leaf stage. Litchi: In mid-November, the leaf surface was sprayed with 15% paclobutrazol wet powder 750 times water. Grape: Spray 1000-2000mg/L liquid at the end of the flowering stage. It can restrain the length of the main shoots and the secondary shoots and increase the yield. Jujube: Spraying the whole tree with 2000~2500mg/L liquid in the 8~9 leaves before flowering can increase the fruit setting rate and increase the yield. Chestnut: If the chestnut grows too much, it will be sprayed with 300mglL in July, which can control the flowering effect. Tips: Paclobutrazol has a long residual time in the soil. Therefore, it is necessary to deepen the land before planting crops. Farmers' friends must pay attention to it.
