Determination of The Efficacy of Some Herbicides on the Weeds in Safflower

Abstract

Safflower is a conspicuous energy crop might be used as a biofuel and raw material source for vegetable oil and animal feed sectors. It has a potential to reduce energy and oil dependency of Turkey reached to a high level due to its capacity. Weeds can cause yield loss because they compete with the crop for water, light, space, and nutrients in safflower. Weed control practices, therefore, should be made efficiently to gain high safflower yield. The aim of this study is to determine the efficacy of pendimethalin, s-metolachlor, and chlorsulfuron to control weeds and the response of safflower to them. The field experiments

Effects of Pre-Emergence Herbicides on Weed Control and Yield of Safflower (Carthamus tinctorius L.) in Central Italy

“…The results of this research showed that s-metolachlor, aclonifen, and propyzamide were the less injurious herbicides for safflower, confirming the results obtained in previous studies [9][10][11][12]17,18]. However, s-metolachlor seemed to be the best option to obtain a good efficacy against the main weeds in the trials, whereas aclonifen and propyzamide failed to control some weeds.…”

“…Furthermore, s-metolachlor had no adverse effects on the safflower, even if it was applied at a dose (2745 g a.i. ha −1 ) higher than that recommended; however, its control ability against Sinapis arvensis L. was limited [18]. Since s-metolachlor has a strong efficacy on grass weeds, but is limited on some broad-leaves weeds, the mixture of s-metolachlor + aclonifen may be worth of testing in further experiments in order to evaluate its selectivity to safflower, increasing its efficacy against broadleaf weeds, due to aclonifen activity, making it more useful to manage the more complex weed infestations typical of the Mediterranean areas.…”
