Monsanto is pleased to sponsor the Weed Resistance Management in Agronomic Row Crops, and Trees, Nuts, and Vines. The purpose of this training is to give you an overview of important management practices that can help avoid or delay the development of herbicide-resistant weeds. We will begin with a brief review of common weed types and herbicides, followed by factors that can influence the evolution of resistance in weeds, and methods for potentially delaying its occurrence in agronomic row crops and permanent crops. While weed resistance management guidelines may be introduced and discussed under a specific annual or perennial crop heading, many of the WRM techniques have cross-crop applicability. When using pesticides for resistance management, always check the label for specific registered uses and the Herbicide Group Number for Mode of Action (MOA), as well as contact your local University Extension Advisor, PCA, and/or manufacture representative.
In production agriculture, weeds or “misplaced plants” have a tendency to tolerate suboptimal conditions much better than most crops. However, they grow more and produce more seed under optimal conditions than they do under suboptimal. For example a nine-foot tall horseweed growing in a vineyard produces 800,000 seeds while a foot tall horseweed growing on a dry, hard road shoulder produces only about 1,000 seeds. Weeds are unwanted plants that compete with crops for nutrients, light and water, and can be detrimental to crop yields. Integrated weed management (IWM) programs and orchard cultural practices have been developed for specific orchard and vineyard crops. This accredited CEU provides information on economically and environmentally sound IWM practices. This course will provide an overview of important weed control and management practices as well as some insight into managing for herbicide-resistant weeds.
This online course covers the management of spray drift to minimize problems. Spray Drift Management (SDM) has been a critical element for Western agriculture for decades. Keeping crop protection chemicals on the crop for which they are intended has been a cornerstone of Western farming not only to protect neighboring crops, but to avoid wasting money by allowing products to drift off the intended target. Spray drift management has taken on greater significance as cities encroach upon rural areas. Every year, increasingly more houses and other types of developments are springing up in prime growing areas, oftentimes alongside fields, orchards or vineyards. This leads to increased concerns about the use of agricultural chemicals and the ways they are applied. This course will review many aspects of spray drift – from practical, hands-on ways to minimize drift, to the regulatory issues surrounding it.
This course discusses mite control in major crops and is sponsored by BASF. Mites are small arthropods in the class Arachnida and the subclass Acari. Although they are related to insects, mites are in the arachnid class and are closely related to spiders and ticks. They are common pests in agriculture, landscapes, and gardens. Mite species are estimated to number nearly 50,000. They live in diverse habitats; in soil, water or plant matter. They eat living and dead plant material as well as fungi, lichens, and even carrion. Some are parasites on animals and others feed on mold. This course will focus on the mites that threaten nut trees, pome fruit, grape, strawberry, tomato, and citrus crops.
This course is sponsored by Western Farm Press. There are an estimated 150,000 named species in the insect group called Lepidoptera. Outnumbered only by the beetles, Lepidoptera represent the second-most diverse order of insect pests, and virtually every cultivated plant is attacked by at least one type. They are ready to defoliate and weaken plants or mine plant tissues, leaving holes and frass behind and rendering crops unmarketable. Their scientific name comes from the Greek Lepidos, for “scale,” and Pteron, for “wing”--literally “scale wing,”--because the wings of adult butterflies and moths are covered with microscopic scales. This course will specifically highlight six lepidopterous pests: the beet armyworm, cabbage looper, diamondback moth, tomato fruitworm, tomato pinworm and western yellowstriped armyworm. The course will also cover managing Lepidopterous pests in a wide array of crops and includes an additional section on Pesticide Safety.
Grape Powdery Mildew is the number one disease in California vineyards. More dollars are spent on powdery mildew control and, yet, this disease still accounts for more crop losses than any other grape pest. This course, sponsored by Western Farm Press, explores the different fungicide classes; treatment options for powdery mildew in California; resistance management, and regional differences in disease development. It also includes a detailed approach to using the UC Powdery Mildew Risk Assessment Index (RAI) to predict infections. Seasonal patterns of disease development differ from region to region (as well as year to year), and cost-effective management strategies must be based on local conditions that favor or inhibit pathogen reproduction. Season-long control depends on reducing early-season inoculum and subsequent infections with well-timed fungicide applications. Spray timing and frequency (and coverage) is everything; these vary depending on local weather, temperature, varietal susceptibility, vine growth stage and material choice.
The 2,000-member Weed Science Society of America's (WSSA) Herbicide Resistance Action Committee has developed this five-module education course, hosted by Penton Media. Due to extensive herbicide use, populations of weeds with resistance to one or more herbicides continue to increase within the USA. To combat the further selection of herbicide-resistant weeds, the entire agricultural community must make an effort to understand herbicide resistance, learn to identify it early, and implement management tactics to delay and mitigate the evolution of herbicide-resistant weeds. Proactive management practices that are designed to prevent or slow the evolution of herbicide-resistant weeds have significant advantages compared with waiting until herbicide resistance is present in the field and implementing reactive management strategies. These training lessons were developed by a team of weed scientists in an effort to provide to you, the agronomist, consultant, retailer or distributor, and interested grower, the most current information on herbicide resistance in weeds.
Biopesticides are increasingly being recommended as components of Integrated Pest Management (IPM) programs in the production of non-organic high-value specialty crops like fruit, nut, vegetable, vine, ornamental and turf. There are about 430 registered biopesticide active ingredients used in a wide array of agricultural pest management products. Biopesticides are derived from natural materials such as animals, plants, bacteria, and certain minerals. Biopesticides are considered an effective pest control option for organic crop production. However, they increasingly are being recommended and used as components of Integrated Pest Management (IPM) programs in the production of non-organic high-value specialty crops such as fruit, nut, vegetable, vine, ornamental, and turf. This online CE course covers the principles for using the 430+ registered biopesticide active ingredients used in a wide array of agricultural pest management products. It is sponsored by Marrone Bio Innovations and includes a Safety Review at the conclusion of the course material.
