Pest Control in Maize Booting Stage

Corn is often found in the jointing stage from the booting stage to the heading stage. Corn borer is a borer pest. The larvae are from the stem and the sheath between the stems and the stems. They feed on the pith and affect the nutrient transport. The damaged plants are not full or even grain-free. The stalks are easily blown by the wind, causing severe production cuts. After the corn leaf is pierced by the larvae, rows of small holes appear on the unfolded corn leaves. The larvae can also be drilled into male inflorescences, often causing the male inflorescence base to break. The larvae often feed on the filaments and tender leaves of the ear, and can break into the cob or eat the young seeds.

 

The following agents should be used to control corn borer: 1.5% phoxim granules, 1 to 2 kg per mu , mixed with fine soil or fine river sand 5 times, sprinkled into the bell mouth; 80% trichlorfon soluble Powder 1000 ~ 1500 times liquid heart, 100 per kg of drug solution ; can also spray 20% fenvalerate EC 400 times solution, or 2.5% deltamethrin ( enemy kill ) emulsifiable oil 400 times solution.

 

At the same time, attention should be paid to the investigation of armyworms and aphids. When the insects reach a certain density, they should be prevented in time. For corn big, small spot disease and rust, it is also necessary to check and control early.
