Evaluation of Fenclorim Safener for Use in Rice with Group 15 Herbicides
… research has demonstrated the utility of acetochlor and pyroxasulfone to provide in-season weed control for Arkansas rice production, but variable crop tolerance has been observed. Additionally, acetochlor at 1,260 g ai ha-1 elicited less rice injury when seeds were treated with a …

Evaluation of Very-Long-Chain Fatty Acid-Inhibiting Herbicides in Arkansas Rice Production
… herbicides pethoxamid, pyroxasulfone, acetochlor, and S-metolachlor were evaluated for rice tolerance and control of commonly problematic weeds in Arkansas rice at various rates and application timings. Pyroxasulfone and S-metolachlor were deemed unfit for use in rice production because …

New Herbicide Strategies for Weed Management in Pumpkin and Soybean and Potato Vine Desiccation
… used for weed control in pumpkin. Fluridone and acetochlor formulations applied preemergence were evaluated in direct-seeded pumpkin compared to other labeled herbicides. Fluridone resulted in total crop loss following heavy rainfall immediately after planting; less rainfall resulted in transient …

Screening of herbicides for selective weed control in African marigold (Tagetes erecta)
… herbicides, topramezone and encapsulated acetochlor, caused minimal visual injury to the crop and encapsulated acetochlor had a minimal effect on plant dry weight. Dry weight response to topramezone varied among experiments. Additional studies were conducted to better define African …

"Determining the Cause of Abnormal Leaf Development ""Leaf Tatters"" on White Oak (Quercus Alba L.), and Northern Red Oak (Quercus Rubra L.)"
… Leaf tatters occurred after treatment with acetochlor + atrazine and metolachlor at the leaf unfolding stage. Leaf tatters did not occur on seedlings treated with acetochlor or metolachlor at the swollen bud or expanded leaf growth stages, or on seedlings treated with 2,4-D, glyphosate, or …

Preemergence activity of chloroacetamide herbicides on a multiple herbicide-resistant population of waterhemp (amaranthus tuberculatus)
… another active ingredient from the same class, acetochlor, remained effective. With such similar observations on geographically separated waterhemp populations, field research began at the CHR location in 2016 to investigate this reoccurring anomaly. Chapter 1 of this thesis includes a …

A Comparison of the Herbicidal Activity of Several Chloroacetamides and Their Effects on Protein Synthesis in Carrot and Soybean Cell Suspension Cultures
The herbicidal efficacy of acetochlor {2-chlor-N-(ethoxymethyl)-6'-ethyl-O-acetoluidide}, alachlor {2-chloro-2',6'-diethyl-N-(methoxymethyl) acetanilide}, metolachlor {2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl)acetamide} and xylachlor …

Physicochemical studies of the inclusion of selected agrochemicals in cyclodextrins
… and the chloroacetanilide herbicide, acetochlor. A study of CD complexation with these pesticides in solution as well as in the solid state was undertaken. A further set of experiments was conducted, whereby the thermal stabilities of three isostructural inclusion complexes were …

Mechanisms and control of waterhemp populations resistant to group 15 herbicides
… An alternative VLCFA-inhibiting herbicide, acetochlor, remained relatively effective. Additional research was conducted to investigate VLCFA-inhibitor efficacy on each population in the field and greenhouse. Experiments identified few effective VLCFA-inhibiting herbicides for controlling …

Avoiding Protoporphyrinogen Oxidase Inhibiting Herbicide Selection Pressure on Common Ragweed and Palmer amaranth in Soybean
… provided similar control to flumioxazin. Acetochlor and linuron controlled common ragweed <74%, yet controlled Palmer amaranth >96%. Glufosinate applied POST controlled Palmer amaranth and common ragweed 74-100%, regardless of PRE treatment. Flumioxazin PRE followed by fomesafen POST …

Evaluation And Characterization of Herbicide Resistance In Italian Ryegrass (Lolium multiflorum Lam.) Biotypes To Diclofop-methyl And Alternative Management Options
… ryegrass control in the greenhouse included acetochlor (two formulations) and flufenacet plus metribuzin. In the field, flufenacet plus metribuzin resulted in excellent Italian ryegrass control, little crop injury, and acceptable barley yields. Acetyl-coenzyme A carboxylase (ACCase) assays …

Weed management in conventional, no-till, and transgenic corn with mesotrione combinations and other herbicides
… in no-till corn. Mesotrione combinations with acetochlor did not always improve control of broadleaf weeds, but increased control of smooth pigweed and giant foxtail (Setaria faberi Herrm.). POST applications of mesotrione at 105 g ai/ha controlled most annual broadleaf weeds except common …

Characterization of HPPD-inhibitor resistance in waterhemp (Amaranthus tuberculatus)
… waterhemp population. Under field conditions, acetochlor, sulfentrazone, flumioxazin, metribuzin, and pyroxasulfone generally provided the highest levels of waterhemp control and greatest reduction in waterhemp density. Chapter 4 also includes a soil-applied mesotrione dose response comparing …
