Making sure they stay on target, for example, is essential. You must take a number of factors into account when applying herbicides. Learn about management and herbicide use for perennial weeds and earn pesticide applicator recertification credits with Penn State Extension’s Problem Weeds in Field Crops: Managing Perennials online courses. Poison hemlock: Penn State Extension’s Poison Hemlock Identification video shows you how to identify this toxic weed.It can be very problematic when left to develop into a thriving stand which has spread into a hay field. Milkweed: Milkweed is a native perennial that exudes a white, milky juice from broken or cut surfaces.It requires an integrated management approach and aggressive weed management strategies to prevent seed production and the spread of these weeds. Noxious pigweeds: Palmer amaranth and waterhemp are two species of pigweed recently introduced into Pennsylvania.You can control it, but it takes considerable effort. Multiflora rose: It was originally introduced from Asia and promoted as a “living fence” but it is now a noxious weed in Pennsylvania and surrounding states.One distinguishing characteristic is its spiky egg-shaped pod. Jimsonweed: This is an annual plant that is poisonous to animals and humans.Grazing animals will rarely eat poisonous weeds, but you should still aim to minimize the risk with careful control. This is especially important for species that are toxic. If you want to control or eradicate weeds in your forage crops you have to be able to identify the different species. Recommended herbicides do not generally injure people, wildlife, livestock, crops, or pasture. Penn State Extension holds a Soybean Management Workshop and Herbicide Demonstration on-site, where producers are given the opportunity to discuss herbicide usage. However, you should only use them when necessary, at recommended rates and times of application, and only for crops and uses listed in the label. Herbicides provide a very convenient, economical, and effective way to control weeds. However, it’s still possible to effectively kill perennial and biennial weeds after a few hard frosts. Fall is an excellent time for the control of biennial weeds. Annual and perennial weeds are best controlled after silage harvest or in fallow areas. Timing plays an important role in a forage weed management system. Other cultural and weed management practices that promote a highly competitive forage stand include seeding vigorous, well-adapted, and long-lived varieties, buying weed-free seed, cutting forage at the right time and growth stage, timely control of insect and disease problems, and rotating crops. Forage stands that are vigorous and dense-growing, for example, have fewer weed problems. There are many forage weed management strategies, but your focus should be on cultural practices, before chemical weed control. Understanding the characteristics of weeds, their life cycles, and keeping up to date with the latest weed control methods means you can choose the best methods for your own forage crop production. Without it, you run the risk of reduced forage yield, lower forage quality, increased incidences of disease and insect problems, premature stand loss, and problems when harvesting. Weed control plays a key role in forage production. Make use of Penn State Extension’s vast resources covering weed control and management of forage crops, common toxic and noxious weeds, and find tips on herbicide application. Weeds in forage crops have an impact on your profit margins because they affect the quality of your forage, reduce yield, palatability, and your grazing area.
