The best time for three times of corn medicine

If you want to grow corn to be high-yielding, you need to give it three times. Some growers still don't know when corn is injected three times. Let's take a look at the best time for corn to be medicated three times.

I. the first time medicine

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.

Second, the second time medicine

Pest control, disease prevention, drought and flood prevention. 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.

Control the occurrence of top rot, the corn eaten by insects, through the wound, it is easy to infect germs, with fungicides used together.

Third, the third dose of medicine

Control prosperity, prevent diseases, and increase production. 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.

Corn three times of spraying time is the above, it is best to spray in this period of time, the effect will be better.
