What kind of medicine does corn play?

In the process of corn growth, it is inevitable to administer medicine, but some growers still do not know what kind of medicine corn is used and when to do it. Let's learn about it together.

1. Herbicide

Hit the herbicide in the corn field, the best use period of the herbicide after the corn seedling, the corn three to five leaf stage, the weed two to four leaf stage, this is the safest, the weeding effect is the best, beyond this range, big grass, small old grass, spray must let the grass take a bath, directional spray, avoid the corn heart, while avoiding the high temperature at noon to reduce the occurrence of drug damage. Weeding at the same time must control planthoppers, thrips, prevent the occurrence of corn rough dwarf disease, but also kill eggs.

II. Insecticides

After 7 days of herbicide, we must control the corn armyworm and drill worm. now the insects on the corn have developed resistance, the general high chlorine, caramicin salt can not be killed, we must first choose high-end insecticides to control, can be used to control mites, insects and mites can be treated simultaneously, and the effect lasts for about 20 days.

Brassinolide and functional foliar fertilizer must be added to prevent and control insect pests, so that the yellow seedlings and weak seedlings caused by herbicides can be repaired, and the weak seedlings caused by Rain Water can be repaired and the growth of corn can be accelerated. It plays a key role in resisting drought, waterlogging and promoting strong seedlings.

Third, foliar fertilizer

The 8-leaf stage of maize is the best period to control prosperity, and it is very important to control prosperity and prevent lodging. At the same time, combined with insecticides, fungicides, brassinolide and functional foliar fertilizer to prevent disease, kill insects and increase production at one time. Conditional pollination essence can be sprayed in the 10-leaf stage of corn, which plays an important role in poor pollination caused by high temperature heat injury, lack of grain and not full grain.

The drug use of corn should be determined according to the actual growth situation, according to the specific growth situation, the right medicine is the best choice.
