What crops does ethephon work on?

Which crops does ethephon have effect on? Ethephon is a broad-spectrum organophosphorus low-toxic plant growth regulator that promotes ripening, which can enter the plant through leaves, bark, fruits and seeds, and then transmit to the active parts and release ethylene. It can promote fruit ripening and coloring, promote leaf and fruit shedding, dwarf plants, change the ratio of female and male flowers, induce crop male sterility and so on. Ethephon is mainly used in rice, corn, Jinqiu pear, grape, peach, tomato, cucumber, melon, cotton and other crops in Zhongfang County. Rational use of plant growth regulators can increase production and efficiency. The main results are as follows: 1. The rice can adjust its growth, dwarf and strengthen the seedlings and increase the yield by spraying 40% water agent 600 / 800 times at the seedling 5-Mel 6-leaf stage (15 Mel 20 days before transplanting). 2. During the small trumpet period, corn was sprayed with 40% water agent 10 ml / mu and 30 kg water / mu, which could regulate the growth and increase the yield. 3. Jinqiu pear was sprayed with 5000 times solution of 40% water for 30 days before harvest, which could promote fruit ripening. 4. In the initial stage of berry ripening, the grape can promote fruit coloring and early ripening by spraying 1000 Mel 2000 times solution once, but when the concentration is high, it is easy to cause fruit drop. 5. Spraying peach fruit with 5000 times of 40% water in the middle stage of hard core can ripen 3 Mel 4 days earlier, and the coloring is early and neat, but the fruit is soft. 6. The green fruit of tomato near maturity can be sprayed with 40% water agent 800Me 1000 times liquid, which can promote fruit ripening and change color earlier. 7. Cucumber and pumpkin can increase female flower and yield by spraying 40% water agent 2000Mel 3000 times at the fourth leaf stage of seedlings. 8. Muskmelon can promote the formation of bisexual flowers and increase the yield by spraying 40% water agent 800 times at the third leaf stage of seedlings. 9. During the boll opening period of 70% Mel 80% cotton, 40% water agent 300 Mel 500 times liquid is sprayed, which can promote boll boll opening and increase cotton yield. Note: ethephon is strongly acidic and cannot be mixed with alkaline substances or diluted with alkaline water. The dosage should be increased at low temperature and decreased at high temperature. The drug has a strong irritating effect on the skin and eyes, so pay attention to safety protection when using it. Click to get more regulator use technology click to get more pesticide use technology
