Prevention and control of corn pests can not only be aimed at aboveground pests, underground pests also affect the normal growth of corn. The common underground pests of corn include tigers, golden needles, cockroaches, cultivars, and aphids. What are the specific drugs for controlling these corn pests?
Tiger
The first is combined with soil testing and formula fertilization, nitrogen control, phosphorus control fertilizer, maintenance of micro-fertilizer, and application of potash fertilizer (with zinc fertilizer, potassium dihydrogen phosphate 3 to 5 kg per acre). The second is to use 3% phoxim particles 2 to 3 kg, available water 3% phoxim, 5.7% cyfluthrin, etc., sprayed over the ground, can also be used 0.5 kg 90% trichlorfon hot water, add water 5 Kilograms are sprayed on sauteed oil dregs and spread around the roots in the evening. 4 to 5 kilograms of baits are used per acre. The third is to take measures such as moth trapping, weeding, pharmacy, and artificial integration to effectively control damage.
Grub
The first is to plow ploughs and kill insects, and it is also possible to turn crops or dry crop rotations. The second is to install black light traps to kill adult worms in the field. The third is to use 0.5 liters of 50% phoxim EC, or 0.5 liters of 40% methyl iso-isopiriol EC, and 10 to 20 bottles of Po Sang (100 ml/bottle, add 20 liters of water) to mix 200 kg of corn. Fourth, add 5 liters of soil and water to 4 hectares of methyl isophosphorous acid per hectare and spray 300 kg of fine moist soil to spray in the seeding ditch.

One is to plow the land. The second is the rotation or dry rotation. The third is to install black light traps to kill adult worms in the field. The fourth is to use 40% dimethoate EC or 90% crystal trichlorfon 0.7 kg, add appropriate amount of water, stir fry bait (bean cake, wheat bran, cottonseed cake, etc.) 50 kg, made bait, dig a 3 to 5 meters every one A large bowl of pits will be covered with a poison bait after each pit in the evening.
Two-pointed moth
The larvae were infested between late June and mid-July. One is bait bait, mu is brewed with 4 to 5 kilograms of sauteed wheat bran or crushed sauteed cottonseed cake, and trichlorfon for a small amount of water (stomach poisoning, both contact), or chlorpyrifos (touch poison, stomach poison) , fumigation) 500 grams mixed baits, in the evening Shun ridge sprinkled corn seedlings. The second is the use of poisonous sand, mu 300 milligrams of 500 milligrams of dichlorvos mixed with 25 kilograms of fine sand, in the morning along the ridge sprinkled in corn seedlings.
Goldworm
Mainly to prevent and control larvae seed dressing, give consideration to the control of the growth period, and pay attention to the trapping and killing of adults. One is to plow the land. The second is the rotation or dry rotation. The third is to install black light traps to kill adult worms in the field. The fourth is to use 0.5 liters of 50% phoxim 0.5 g, or 40% of methyl iso-isopiriol 0.5 l, 10 to 20 bottles of Po Sang (100 ml/bottle), 20 liters of water, and 200 kg of corn.
Colored sticky corn is generally white, yellow, red, purple and black, among which white, yellow and purple corn are the basic colors. If the purple gene of the purple-white hybrid "beats" the white gene, it will naturally become purple, and vice versa, so if the two are tied, we will see white and purple corn. Purple can become red and black corn, or as we often say, "red is purple and black is purple".
Among these colorful corn, the most common Yellow Waxy Corn is the most nutritious because it is rich in carotene.
