The suggestions contained herein are based primarily on herbicide labels, research by Texas AgriLife Research and demonstrations by Texas AgriLife Extension Service. The use of product names is not intended as an endorsement of the product or of a specific manufacturer, nor is there any implication that other formulations containing the same active chemical are not equally as effective. Product names are included solely to aid readers in locating and identifying the herbicides suggested.

The information provided in this publication is for educational purposes only. Reference to commercial products or trade names is made with the understanding that no discrimination or endorsement is intended and no endorsement by Texas AgriLife Extension Service, Texas AgriLife Research or Texas A&M University is implied.
This publication is no substitute for the herbicide product labels! It is intended to serve only as a guide for controlling weeds in pasture and forages. Labeled rates and restrictions change constantly, therefore, consult the product label before use.

Weeds can be controlled in cropland through cultural, mechanical and chemical means. Wise use of these individual methods or a combination of them manage weeds effectively without causing economic loss or harming the environment. Deciding which practice to use will depend largely on the weed(s) being controlled and the infestation level. Also, the crop being planted will play a major role in determining when to use mechanical measures.

Considerations for cultural and mechanical weed control include:

  1. Remove light or spotty infestations of weeds by hand hoeing or spot cultivation to prevent spreading weed seed, rhizomes or roots. Exercise caution when plowing perennial weeds, being careful to prevent the transport and spread of plant parts to other areas of the field.
  2. Use weed-free planting seed to protect against weed infestations in the row and the introduction of new weed species.
  3. Thoroughly clean harvesting equipment before moving from one field to the next, or require it of the custom harvesters before they enter your fields.
  4. Use mechanical tillage to remove initial weed flushes prior to planting, thereby eliminating or at least reducing the potential for continued infestation.
  5. Consider the economics of using mechanical cultivation alone for weed control in the crop, especially where annual weed infestations are light.
  6. Practice rotation to crops that physically out-compete certain weeds, resulting in their gradual decline.
