According to observations, from 5–7 July this year the second egg-laying of the corn borer, one of the most harmful pests of this crop, will begin in corn crops. 10–12 days later mass hatching of larvae will start. Given this, entomologists recommend treating corn crops with insecticides in this period. Insecticides combine well with special fertilizers in a tank mix, so it is possible to feed corn with the necessary nutrients depending on plant condition.
In this period 3 main nutrition problems usually appear on corn:
The first is hidden boron deficiency. Its shortage shows as gaps in the rows of kernels, a consequence of insufficient viability of pollen grains. The problem is easily eliminated by foliar feeding of plants with the special fertilizers ECOLINE Boron (Organic), or ECOLINE Boron (Premium) at 0.5–1.0 l/ha. Boron feeding in this period promotes accumulation of sugars, one of the main building materials in the plant.
The second problem is potassium deficiency. It shows visually first as paling of the edges of the leaf blade and then drying of the whole leaf. It is observed first on lower leaves and then spreads to leaves of the next tiers, which seriously lowers the plant's yield potential. Leaf drying can be halted by foliar feeding with the special fertilizer ECOLINE Phosphite (K) at 1.0–1.5 l/ha.
The third problem is hidden deficiency of microelements and potassium. For this we recommend using the complex fertilizer ECOLINE Corn (Chelates) at 1.0–2.5 l/ha.
