Weeds are likely to emerge with the corn in many fields due to the lack of herbicide. The presence of weeds could be attributed to the weather constraints and it is critical to control weeds in order to protect the corn yields. In places like Louisiana the farmers are facing a biggest problem of weed control. Their yields have slipped due to weeds and they are facing losses. Some of the fields are very weedy and no amount of herbicide can get a good yield. This has been a worry to corn growers and a constant fear lurks in their minds. Weeds grow in a hurry and no amount of removal helps. They grow again even before a corn plant grows.
The term critical period is utilized to determine for how long the weeds will be allowed to compete with the crop till the corn gets damaged. To obtain maximum yield, weeds must be eradicated before they reach the critical period. Timely weed management to protect the corn plants is a fundamental feature for all crop growers and is majorly undertaken to maximize the corn yield potential. Killing the weeds is an essential step to achieve the goal of weed management.
To control any weeds that crop up in the patch, you must hoe between the rows. Make sure you don't hoe too deep or you may damage the stalks and roots. You can also spread mulch around the base to control the weeds and help to conserve the moisture. The concern for timely weed management in order to protect your corn yield becomes crucial in the post emergence herbicide corn systems and most research universities recommend the use of herbicides in the earlier pre plant and pre emergence period as an excellent option to reduce weed management risks. The purpose of the soil applied herbicide treatment is to moderately reduce the weed pressure, thereby allowing corn to achieve a superior growth posture.
A 100% season ling weed control is the ultimate goal of a soil applied herbicide treatment. The weeds that are generally targeted include giant foxtail, woolly cup grass, small seeded annual broadleaf weeds and giant ragweed. Weeds are as painful and irksome as pests and insects that infest the corn plants. All the necessary measures must be undertaken to rake off all these pests that may prove hazardous to your corn yield.
