MİNİMAZİNG POTENTİAL PHYTOTOXİCİTY RİSK OF OXYFLUORFEN MİSUSED ON SUNFLOWER BY PLANT ACTİVATOR

Project no. 21120 · Status: Kapanmış (Yayın bekleniyor) · 2020

Summary

In this study, it was aimed to investigate the effect of the plant activator on the elimination of the negativity by revealing the negative (phytotoxicity) effects caused by the misapplication of the herbicide with the active substance oxyfluorfen. Herbicide with oxyfluorfen effect from 2 different companies, 2 different amounts of water (20 and 40 L/da), application days (0, 1, 2, 3, 4, 5, 6, and 7th day), activator (Crop Set) The experiment used was set up with 4 replications. Phytotoxicity assessments were made on the 5th, 10th and 15th days after the application. Evaluations were carried out using the number of plants per unit area and the phytotoxicity scale. The application of the active substance Oxyfluorfen in the first 4 days of sowing carries less risk in terms of phytotoxicity. The activator applied to the seed reduces the risk of phytotoxicity by 48.30%-93.5% compared to the application without activator. Activator application after the emergence of the first true leaves showed a success rate of 60.61%-93.31%. Key Word: Oxyfluorfen, sunflower, phytotoxicity, plant activator
