field experiments were conducted to evaluate the effect of thiobencarb and oxadiargyl herbicides on rice (oryza sativa l.) and their possible residual effects on spinach (spinacea oleracea l.) and lettuce (lactuca sativa l.) at dashtnaz and gharakhil agricultural research stations, iran. treatments included thiobencarb at 3.16 and 6.33 kg a.i. ha-1, oxadiargyl at 0.15 and 0.30 kg a.i. ha-1 and ...

Reniform nematode (Rotylenchulus reniformis) resistance is being transferred to Gossypium hirsutum from its distant relatives. Reports of fluometuron damage to LONREN lines with nematode resistance from G. longicalyx raised concerns about introducing herbicide sensitivity from other nematode resistance sources. The research objective was to evaluate 15 sources of reniform nematode resistance fo...

Many large-scale management programs directed toward the control of waterhyacinth rely on maintenance management with herbicides. Improving the implementation of these programs could be achieved through accurately detecting herbicide injury in order to evaluate efficacy. Mesocosm studies were conducted in the fall and summer of 2006 and 2007 at the R. R. Foil Plant Science Research Center, Miss...

A field study was conducted in 2015 and 2016 Stoneville, MS, to evaluate the influence of cytokinin products on soybean injury weed control when combined with common POST herbicide treatments. Cytokinin treatments included no mixture two formulated mixtures (kinetin-1 kinetin-2) applied at 0.000227 kg ai ha−1. Herbicide were herbicide, glyphosate 1.37 ae ha−1 alone combination S-metolachlor 1.4...

The emergence of herbicide-resistant weeds is a major threat facing modern agriculture. Over 470 weedy-plant populations have developed resistance to herbicides. Traditional evolutionary mechanisms are not always sufficient to explain the rapidity with which certain weed populations adapt in response to herbicide exposure. Stress-induced epigenetic changes, such as alterations in DNA methylatio...

The objective of this study was to compare FirstAct with several tank mix partners for efficacy in herbicide-tolerant grain sorghum. (quizalofop) alone or mixtures controlled Johnsongrass 94% more. However, mixing any broadleaf herbicide generally antagonistic Palmer amaranth control. Minor sorghum injury 5% less by four weeks after postemergence treatment. Sorghum yields increased all treatmen...

This research was conducted to determine the efficacy of quizalofop (FirstAct) herbicide in herbicide-tolerant grain sorghum. FirstAct evaluated for and crop response Double Team (ACCase-tolerant) All herbicides controlled Palmer amaranth 90% or more volunteer corn 95% late season. Johnsongrass control 86 91%. Minor sorghum injury early season did not persist. Sorghum receiving postemergence yi...

Background In the last two decades, herbicide-resistant biotypes of Conyza bonariensis, canadensis, and sumatrensis were identified. Objective: To evaluate herbicide alternatives for control C. to replace simplified management at soybean pre-sowing in no-till system assess potential injury soybeans. Methods Four experiments conducted Palotina, PR, alternative managements herbicides commonly use...

Abstract XtendFlex® technology from Bayer allows growers to apply glyphosate, glufosinate, and dicamba POST cotton. Since the evolution spread of glyphosate-resistant weed species, early applications with several modes action have become common. However, crop injury potential these warrants further examination. Field studies were conducted 2015 2017 at two locations in Mississippi evaluate cott...
