Abstract

A field study was conducted to evaluate the compatibility of herbicide tank mixtures in winter wheat (Triticum aestivum L.) Sagittario cv. in 2017-2019. Weed Index (VI) and Crop Injury (CI) of three mixtures prominent was recorded with mesosulfuron-methyl plus 2.4-D ethylhexyl ester + florasulam (5.8% and 1.5%) followed by pyroxsulam + florasulam  + cloquintocet-mexyl plus 2.4-D dimethylamine salt (6.3% and 1.6%), and mesosulfuron-methyl + iodosulfuron-methyl-sodium plus bromoxynil + MCPA (7.1% and 0.0%), respectively. Weed Control Efficiency (WCE) was maximum with mesosulfuron-methyl + mefenpyr-diethyl plus 2.4-D ethylhexyl ester + florasulam so, Cirsium arvense (90%) heavily damaged; Avena fatua (98%), Avena sterilis (94%), and Papaver rhoeas (96%), Sinapis arvensis (95%) very heavy damaged (severe chlorosis and/or dead leaves); Galium aparine, Phalaris brachystachys, and Ranunculus arvensis were completely killed (100%, dead). Consequently, mesosulfuron-methyl + mefenpyr-diethyl plus 2.4-D ethylhexyl ester + florasulam herbicide mixture is recommended to provide weed control efficiency and wheat production safely. The compatibility of herbicides is necessary for sustainable weed management as it leads to reduced input costs, to prevent economic losses and to less pollution of the ecological environment. In addition, the conditions may require that the herbicides be applied with fungicides, insecticides or foliar fertilizers, and growers wish to know the safety of these mixtures. Therefore, studies on the compatibility of chemicals used in agriculture were considered to be needed.
