Apart from simply disrupting the beautiful smooth green of the field near your home, many types of weeds spread quickly, aggressively beating out grasses for available nutrients and water. Some weeds—such as pokeweed, horse nettle, and perilla mint—are even poisonous to livestock. The bitter taste of many poisonous plants may discourage livestock from eating them, but during dry spells even bitter weeds can be tempting. Some trees and brush can be just as invasive as smaller weeds. To name a few, cedar, oak, persimmon, and sumac can spread through a field in just a few years, making it difficult to mow or even walk.
The weed treatment plan you employ will depend on several factors: the type of weeds, the density of weeds, and the size of area being treated. The type of herbicide you use will, of course, depend on the type of weed you’re battling. Also, some herbicides are applied to the plant itself and others to the ground. If a problem weed has not yet spread over a large area, you may be able to get away with simply treating individual plants with a small handheld sprayer. For large areas, using a boom sprayer—either handheld or mounted on farm equipment—is advisable for even, efficient coverage.
Brush herbicides have to be absorbed into the stem/trunk of the plant. Either cut a notch in the tree or cut it down entirely and then spray an even coat of appropriate herbicide over the freshly exposed wood. If you wait too long before applying the herbicide, the tree will start healing and form a barrier that will keep out harmful substances.
Gregg Farm Services provides a large variety of herbicides for home and pasture use.
