What are the functions and usage of paclobutrazol?

What are the effects of paclobutrazol? How to use paclobutrazol? Also ask experienced netizens to help introduce the use of paclobutrazol in planting rice, wheat, peanuts, fruit trees, tobacco, rape, soybeans and other crops, but the specific role and detailed use of paclobutrazol, there are many netizens are not very clear, so the farming network sorted out the role and use of paclobutrazol, listed below in detail for netizens' reference. The function of paclobutrazol: paclobutrazol is a triazole plant growth regulator and an inhibitor of gibberellin synthesis. It mainly inhibits gibberellin biosynthesis in plants, slows plant growth, controls crop stem elongation, shortens crop internodes, promotes plant tillering, promotes plant flower bud differentiation, increases plant stress resistance, and increases yield. The use of paclobutrazol: first, the method of using paclobutrazol in rice: 1. During the one-leaf period of rice seedlings, 100 kg of paclobutrazol aqueous solution with a concentration of 0.0003% per mu was evenly sprayed on rice seedlings, which can effectively control the seedling height and cultivate rice seedlings with many tillers and strong rooting ability. 2. After rice transplanting, during the panicle differentiation period, 10% paclobutrazol wettable powder 180g/ per mu was sprayed with 50L / mu of water, which could inhibit the elongation of rice stem, make the Internode short and sturdy, so as to prevent lodging and promote yield. Second, the method of using paclobutrazol in soybean: for vigorous soybean, 0.0002% paclobutrazol solution can be sprayed at the early flowering stage of soybean, which can effectively regulate the plant type of soybean, prevent excessive growth and lodging, and reduce the loss of nutrients. in order to promote branching and increase production. Third, the method of using paclobutrazol in rape: it is generally used in the period of rape seedlings growing to three leaves and uniformly spraying with 40-50 kg paclobutrazol solution with a concentration of 0.00015% per mu, which can effectively cultivate strong rape seedlings and prevent the occurrence of tall seedlings. promote the survival rate of rape after transplanting, and have a certain anti-freezing effect. Fourth, the method of using paclobutrazol in fruit trees: paclobutrazol is mainly used in soil treatment, trunk coating and foliar spray. But the effect of soil treatment is the best. Soil treatment with 10% wettable powder per cubic meter of tree crown 10g 15g, in the form of similar annular fertilization ditch, wide 30cm, deep 20cm, with root exposure without root injury as the principle, sprinkle the medicine into the ditch and cover the soil. Watering before and after application to maintain soil moisture. The dry method of painting fruit trees can be dried with 10% paclobutrazol wettable powder 150-300 times. The foliar spray method was used with 15% wettable powder 75-150 times liquid foliar spray for young trees, which can make the crown dwarf and compact, blossom and bear fruit early, and for adult trees, it can restrain shoot growth, increase yield and improve quality. Points for attention in the use of paclobutrazol: 1. Because the residual period of paclobutrazol in soil is very long, excessive use of paclobutrazol in some field crops or vegetable fields will often affect the growth of subsequent crops. Therefore, attention should be paid to the selection of follow-up crops. 2. In general, the use of paclobutrazol on the table will not cause drug damage to crops, but when the crop produces excessive inhibition when the dosage is too much, it can be rescued by applying more nitrogen fertilizer or spraying gibberellin. 3. Paclobutrazol peanuts can be used at most once, and the safe interval is 60 days. Paclobutrazol was used at most once in rice. What is the effect of ethephon on pesticides?
