This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Widespread adoption of genetically-engineered, herbicide-resistant (HR) crops have simplified crop rotation diversity and the use of single-tactic, herbicide-based weed management programs. These practices have resulted in an HR weed epidemic, where glyphosate-resistant weeds are especially problematic. Glyphosate-resistant weeds like horseweed [Conyza canadensis (L.)] and pigweeds (Amaranthus spp.) threaten grower productivity and long-term efficacy of common agronomic herbicides. Thus, integrated weed management (IWM) programs that implement both ecological- and herbicide-based tactics are needed in no-till annual grain systems to (1) manage current HR weeds, (2) reduce HR selection pressure for evolution of resistance to other herbicides, (3) preserve effective herbicide technology, (4) enhance environmental stewardship, (5) safeguard soil conservation gains, and (6) maintain farm profits and productivity. To address these goals, we established three field studies at two sites in the Mid-Atlantic and identified combinations of cover crop and herbicide tactics that achieve effective season-long annual weed management, minimize HR selection pressure, and increase sustainability by reducing herbicide inputs. The first two studies assessed the complementarity of cover crops treatments and herbicide programs in corn and soybean, where integrating a cover crop treatment combined with applying a spring, pre-plant burndown herbicide application as well as a POST-emergent application provided the most effective season-long annual weed control. The third study assessed cover crop treatments and varied management practices, such as planting and termination dates, on HR selection pressure reduction at the time of herbicide applications. While cover crops intercepted a portion of the burndown herbicide application from reaching the soil surface, weeds were effectively controlled by the cover crops before the application, thus reducing the HR selection pressure.

Book Synopsis Mechanical and Thermal Weed Control in Organic Crops by : Ricardo Costa Silva

Available in PDF, EPUB and Kindle. Book excerpt: Effective weed control is one of the most yield-limiting factors in organic corn and soybean production. Additionally, the amount of tillage needed to control weeds in organic practice is often criticized for its negative impacts on soil quality. This research was conducted in central Missouri from 2016-2017 to compare cultivation, flame application, between-row mowing, and hot water spray for in-season weed control in organic corn and soybeans. Between-row mowing and hot water application were paired with notillage and a crimped winter cover crop of cereal rye (Secale cereale L.). When weeds reached 10.2 cm, weed control practices were implemented and repeated as necessary until canopy closure. Grass and broadleaf weed biomass between crop rows was determined at multiple dates throughout the 2016 and 2017 seasons and in-row weed levels were determined at the final collection date for each crop each year. Broadleaf weed biomass at the end of the soybean season in 2016 was lower in the two treatments utilizing no-till and cover crops as primary weed control and hot water and mowing as secondary control. Soybean yield was adversely affected by flaming but not significantly different for the cultivation, mowing and hot water treatments. In 2017, soybean had less between-row grass biomass in the cultivation and flaming treatments than in hot water and mowing, but broadleaf levels were the same in the mowed treatment as the cultivated and flamed treatments. In 2016, grass biomass was lower in the no-till treatments between corn rows and higher in the crop rows than the other two treatments. Weed control treatments led to no significant differences in corn yield in 2016 and higher yields in the no-till treatments in 2017. In-row weed levels were significantly higher in corn in 2017 for the hot water treatment. Hot water at the levels applied in this research was not an effective weed control method. Since the overuse of cultivation can decrease soil organic matter levels and increase soil erosion, alternatives techniques are important to grant farmers the possibility to use their land for a long time. The crimped cover crop used in the no-till treatments limited weed growth in early-season corn and soybean and when coupled with between-row mowing is a potential alternative to cultivation in organic crop production. Flaming is also a potential alternative to cultivation in corn production.

Available in PDF, EPUB and Kindle. Book excerpt: Field studies were initiated in central (Columbia) and northeast (Novelty) MO in fall 2001 and 2002 to examine the efficacy of fall applied herbicides for management of winter annual weeds in no-till corn and soybean. Applications of fall applied herbicides were made in November of 2001 and 2002. Spring applications of different mixtures containing glyphosate were made 14 to 7 days before planting or at planting. The data showed that fall applied herbicides can be very effective in controlling winter annual species identified in these trials. There are a number of herbicides that are effective in controlling these weeds, however, when residual activity of fall applied herbicides is insufficient, spring emerging winter annual weeds or early summer annual emergence should be controlled with a spring burndown or preplant application. However, potential problems from winter weed residues in the spring may delay planting due to slowing of soil drying. Additionally, growth chamber studies were conducted to examine the effect of different air temperatures (4 to 32 C) on the germination of three common winter annuals: common chickweed, henbit, and downy brome. Our data showed that increasing temperatures resulted in higher germination between 13 and 18 C for common chickweed and henbit, respectively. Emergence of downy brome occurred under a broader range of air temperatures than common chickweed and henbit, but all three weeds exhibited temperature plasticity for germination.

Download or read book Agronomic and Pest Interactions in No-till Corn and Soybean Wih Fall Versus Spring Herbicide Applications written by Nicholas Monnig and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fall herbicide applications have increased in popularity in recent years. Little is known of how fall herbicide applications impact soil conditions, insect populations, and winter and summer annual weed populations. Few studies have directly compared fall herbicide applications to early spring applications. Therefore, field experiments were conducted in both no-till corn and soybean fields from 2004 through 2006 in central, northwest, and northeast Missouri. Herbicide applications were made in the fall and at three spring timings. Two residual and one non-residual herbicide treatment were applied at each of the four timings. Removal of winter annual weeds with the three herbicide treatments led to an increase in soil moisture just after planting, and a decrease in insect populations and feeding well after planting. Measurements of soil temperature indicated that removing winter annual weeds could increase temperatures in the spring. Fall residual herbicide treatments provided the highest level of winter annual weed control, yet provided poor control of summer annual weed species after planting. Residual herbicide applications made at the last spring timing provided the highest level of summer annual weed control, yet provided poor winter annual weed control at planting. Residual herbicide applications made one to two months prior to planting offered the best balance between winter and summer annual weed control. Based on the results of these experiments, no-till corn and soybean producers can obtain maximum weed control and planting conditions by applying a residual herbicide in the early spring rather than the.
