【Plant Protection Technology】YIMUSHEN reminds you: the precipitation increases in July, and corn must be controlled as soon as possible if you want to increase production and control prosperity

As of July, the growth of corn in most areas has entered the peak control period. If not controlled in time, it may lead to too tall plants, underdeveloped roots, and increased risk of lodging, which may affect the yield and quality of corn.

01 The importance of Wangwang
Robust stalks: Controlling the stalk can promote the thickness of corn stalks and enhance the ability to resist lodging.
Well-developed root system: The maize root system will be more developed after vigorous control, which will improve the ability to transport water and nutrients.
Yield increase effect: By controlling the prosperity, the 100-grain weight of corn can be increased and the yield can be improved. Improve ventilation and light transmission: Controlling the prosperity can improve the ventilation and light transmission conditions of corn fields, increase the pollination rate, and reduce the bald tip and empty plant rate.
Promote the development of fruit ears: Controlling the growth of fruits helps nutrients to move to the ears, reduces the situation of empty trees and bald tips, and promotes the development of fruit ears.

02  How to judge the peak control period
To determine whether corn has entered the peak period, it can be done by observing the number of leaves and the growth of the plant. The best period for corn control is generally when corn grows 6 to 10 leaves, especially when 7 to 10 leaves, this period is also called jointing stage. So how to tell if corn is 6 leaves - commonly known as "five light and six hairs". That is, the corn leaves with 5 leaves or less are smooth, the first leaf with fluff is the 6th leaf, and the leaves with 6 leaves or more begin to grow hairy and feel astringent when touched.

03  The harm of controlling prosperity too early and too late
Premature control: Premature control may lead to abnormal shrinkage of corn plants, which can not only effectively prevent lodging, but may lead to poor growth of corn and eventually reduce yield.
Late control: If the control time is too late, such as more than 12 leaves of corn, that is, after the jointing stage, it may affect the normal differentiation of corn ears, resulting in a decrease in pollen quantity, and then affecting the pollination quality.

04  Prosperity control measures
Reasonable fertilization: Excessive fertilization should be avoided during the peak period of corn, so as not to cause excessive growth of plants. Necessary medium and trace elements, such as zinc, boron, etc., should be appropriately supplemented to help promote root development and improve the lodging resistance of plants, which are essential for the growth and development of maize. Use of pesticides: If corn grows vigorously, it can be used to inhibit the rapid growth and promote the plant to be more robust.
Soil management: Maintain loose and well-drained soils to avoid root diseases caused by excessive moisture.

Pest control: At the same time of fertilization, pay attention to the prevention and control of pests and diseases to avoid the occurrence of pests and diseases caused by improper fertilization.
