The lack of pre-emergence herbicide often encourages weeds to grow in corn fields. Weather constraints often cause the presence of weeds, and it is essential that you control weeds in order to protect the corn yields. In some places, including Louisiana, the farmers are experiencing enormous problems with weed control. Due to this, corn production has slipped, causing the farmers to face losses. Many of the fields are too weedy and no amount of herbicide can get a good yield. This has been a worry to corn growers and constant fear lurks in their minds. Weeds grow in a hurry and no amount of removal helps. It's easy for the to return even before a corn plant has the change to grow.
The critical period is used to describe the length of time that weeds are allowed to compete with the crop until the latter is damaged. To obtain maximum yield, all weeds must be removed 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.
Hoe between planted rows if you want to control any weeds that crop up unexpectedly. Be careful about digging the hoe too deep – this will damage the corn's 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. 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. One important result of soil applied herbicides is that they promote good plant posture by reducing the pressure applied by the weeds.
One of the important concerns of agriculture researchers is the protection of corn from toxic fungi. If a bacterium is found then it’ll be a boon for farmers to protect their corn against weeds and other pests. Corn growers can sigh of relief now that the U.S. Environmental Protection Agency has recently approved Balance Flexx herbicide from Bayer CropScience. These chemicals help farmers control over 50 varieties of weeds. This protects corn from weeds. It takes down some of the field’s toughest weeds, including kochia and woolly cup grass, while still providing excellent crop safety. It also works through the roots and shoots of weeds to provide exceptional burn down and enduring control.
A 100% 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. Similar to the pests that attack and ruin the corn, the presence of weeds is very unpleasant. It's important to do all it takes to avoid the infestation of pests and weeds that will ruin your corn.
