This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preemergence (PRE) herbicides are used to control weeds and reduce pressure on postemergence (POST) herbicides. However, knowledge of length of control each herbicide provides, as well as the amount of activation rainfall required for adequate weed control, is unknown in Mississippi soybean production. Twenty-one PRE applied soybean herbicides were evaluated for their duration of residual control for five weeks over twelve site years on three weed species from 2021-2022. Some differences in control following herbicide application used on certain weed species were observed at different times. However, most PRE herbicides resulted in adequate (greater than or equal to 90%) control of weed species evaluated up to 35 days after emergence. Also, four PRE herbicides were evaluated in the greenhouse to quantify the amount of rainfall needed for activation when applied to three different soil textures. These data suggest that rainfall recommendations vary by herbicide and soil texture, and some herbicides were effective at controlling weed species at low rainfall amounts (less than 12.7mm).

Download or read book Mitigating Herbicide Impacts to Soybean written by Grant Lawson Priess and published by . This book was released on 2019 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapidity in evolution of herbicide-resistant weeds and the resulting cost to U.S. farmers demonstrate the need to responsibly steward the limited number of herbicides available in agricultural systems. To reduce weed emergence and likewise added selection pressures placed on herbicides, early-season crop canopy formation has been promoted. However, impacts to soybean following a potentially injurious herbicide application have not been thoroughly evaluated. Therefore, field experiments were conducted to determine whether: 1) soybean injury from metribuzin or flumioxazin delayed canopy formation or changed the incidence of pathogen colonization; 2) residual herbicides applied preplant reduced the potential for soybean injury and achieved the same longevity of weed control as herbicides applied at planting; 3) POST-applied acetolactate synthase (ALS)- and protoporphyrinogen oxidase (PPO)-inhibiting herbicides alone and in combination with glufosinate delayed canopy formation or impacted grain yield. Few interactions between herbicides and soil-borne pathogens were observed. Results from various experiments showed that soybean canopy formation was delayed after an application of preemergence (PRE)-residual herbicides and postemergence (POST)-foliar-active herbicides. However, delays in crop canopy formation caused by a PRE application of metribuzin and flumioxazin were only observed in varieties with sensitivity to the herbicide. Soybean injury caused by PRE applications were mitigated by applying herbicides 14 days prior to planting. Treatments that were applied 14 days prior to planting and contained an effective herbicide with a half-life greater than 70 days suffered no reduction in longevity of Palmer amaranth control when compared to the same herbicide applied at planting. POST-applied herbicides delayed soybean canopy formation relative to the amount of injury present following application. Delays in canopy formation can result in a lengthened period of weed emergence, subsequently increasing the need for additional weed control and increasing selection pressure on sequentially applied herbicides. Nomenclature: Flumioxazin, glufosinate, metribuzin, Palmer amaranth, Amaranthus palmeri (S.) Wats., soybean Glycine max (L.) Merr. Key words: Acetolactate synthase (ALS)-inhibiting herbicides, canopy formation, half-life, herbicide-resistance weeds, POST foliar-active herbicide, preplant, protoporphyrinogen oxidase (PPO)-inhibiting herbicides, PRE-residual herbicide, soil-borne pathogen, soybean injury.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrated weed management and herbicide application practices were assessed in field and greenhouse studies to improve weed control in herbicide-resistant soybeans (Glycine max (L.) Merr.) grown in Kansas. The field study was conducted to evaluate weed control, soybean yield, and profitability in two herbicide-resistant soybean systems and two row spacings. 2,4-D-, glyphosate-, and glufosinate- resistant (Enlist E3) and isoxaflutole-, glyphosate-, and glufosinate- resistant (LLGT27) soybeans were planted in 38- and 76-cm row spacing for four site-years. Three herbicide treatments were evaluated in each system: pre-emergence herbicide only (PRE), PRE followed by early post-emergence (POST), and POST plus overlapping residual (POR). Weed control was evaluated every 2 weeks after PRE application through R7 soybean. Weed biomass was collected before POST applications and at R7 soybean. Soybean yield was recorded at harvest. Data were subjected to analysis of variance and means separation. In Ottawa during 2020, POST and POR treatments resulted in ≥ 99% control for all species four WAT, while PRE resulted in ≥ 84% control. Similarly, control at Ashland Bottoms was ≥ 90% for POST and POR treatments, while PRE resulted in 7% for isoxaflutole- 62% for 2,4-D-resistant soybeans. All treatments resulted in ≥ 95% control at Scandia in 2021. Row spacing had a minimal effect on weed control and mixed results for yield. In the greenhouse study, the objective was to determine the effect of herbicide combination, optimize carrier volume, and evaluate weed height on weed control. Co-applications of combinations of 2,4-D choline, glyphosate, and glufosinate were applied in carrier volumes of 93-, 140-, and 187- L ha−1to 5-, 10-, and 20-cm Palmer amaranth (Amaranthus palmeri S. Watson) and large crabgrass (Digitaria sanguinalis L.). Visual ratings and above ground biomass were collected four weeks after treatment. Water-sensitive paper was also sprayed with the same herbicide combinations and carrier volumes to evaluate differences in spray coverage. Data were subjected to analysis of variance and means separation. Carrier volume did not affect Palmer amaranth or large crabgrass control. Control of 5-, 10-, and 20-cm Palmer amaranth was 100%, ≥ 91%, and 6.7 to 79%, respectively, and variation was caused by the herbicide combinations. 2,4-D plus glyphosate provided the greatest Palmer amaranth control. Large crabgrass control pooled for both experiments was ≥ 82% when treatments were applied at 5 cm, but control of 10- or 20-cm large crabgrass was reduced to 51 to 56%. There was a carrier volume by herbicide co-application interaction for the number of droplets deposited and percent area covered on water-sensitive paper. Co-applications containing glufosinate had more droplets than those not containing glufosinate. 2,4-D plus glyphosate had the smallest percent area covered, compared to the other herbicide co-applications. Data from the field study confirms that two-pass herbicide programs are superior to PRE- only programs, regardless of the inclusion of a layered residual herbicide. However, this research did not evaluate the impact of layered residual herbicides on weed seed production, which is crucial for long-term weed management. Results from the greenhouse study suggest that under ideal conditions, carrier volume is less important than herbicide combination and weed size for control of Palmer amaranth and large crabgrass.
