In the past few years, in order to prevent the plant height of the corn from being too high, and the problems caused by lodging, inconvenience in harvesting, etc., most farmers adopt the method of spraying chlormequat pesticides , but the effect is not obvious because the spraying method or time is not correct.

Chlormequat is a synthetic growth inhibitor that inhibits the elongation of crop cells, making crop internodes shorter, thicker, and greener in leaves. Applying a suitable concentration of chlormequat to corn production can improve population structure, reduce plant height, and increase corn yield. It is usually necessary to decide whether to spray according to the growth of corn in the field during the jointing stage, and not to spray the plants that are weak in the growth, low in plants and yellow in the leaves, so as not to affect the normal growth of the corn. The pesticide network suggests that Wangchangtian can generally use 20 ml of water per acre to 30-40 kg of water, and make an aqueous solution of corn chlormequat with a concentration of 600-800 ppm, spraying the top leaves of corn plants. In addition, in the 11-14 leaf stage of corn, 40 ml of corn chlormequat per acre is evenly sprayed on the upper leaves of corn, which can control plant height, promote ear differentiation, and increase the rate of seeding and seed setting. The period is right, and it can't be sloppy when spraying. It is recommended to choose the weather in sunny weather and no wind, and the dose must be controlled.
In the early stage of maize jointing, the use of biological pesticides such as chlormequat is effective for preventing lodging. When the height of corn is 1 meter, it has exceeded the initial stage of jointing. At this time, the application is less effective in prevention.
