Sodium nitrophenolate|Amine fresh ester|Naphthalene acetate sodium phytotoxicity symptoms, sodium nitrophenolate, amine fresh ester, DA-6 and sodium naphthalene acetate are common regulators. When different plant growth regulators occur, The symptoms are also different. Zhengdao Fertilizer Network Xiaobian teaches you to distinguish the following common plant growth regulators from the symptoms of phytotoxicity:
Symptoms of sodium nitrophenolate phytotoxicity: mild phytotoxicity symptoms inhibit plant growth, young fruit dysplasia; severe phytotoxicity is plant wilting, yellowing until death. The phytotoxicity of sodium nitrophenolate occurs less frequently, mainly in sensitive crops such as peach trees and watermelons, causing crops to fall, fruit, and hollow fruit.
Symptoms of a-naphthaleneacetic acid phytotoxicity: The phytotoxicity of mild naphthaleneacetic acid is characterized by defoliation of flowers and young fruit, which has little effect on plant growth. The heavier phytotoxicity is that the leaves are atrophied, the petioles are turned over, the leaves are shed, and the results are rapidly matured and shed. For soaking seeds, the roots are less, the roots are deformed, and the roots are not rooted, and no seedlings are produced. The a-naphthalene acetic acid medicinal part will have phytotoxic effects on the lower crops, and most of them will not cause harm to the lower crops.
DA-6 (amine fresh fat) phytotoxicity symptoms: leaves are spotted, then gradually enlarged, light yellow gradually turns dark brown, and finally transparent, DA-6 (amine fresh fat) only appeared on peach trees There have been no phytotoxics on other crops so far.
