Maize
Magnesium deficiency
Symptoms: Leaves show advanced interveinal chlorosis, necrotic edges. In severe cases it leads to shortening of the internodes.
Affect: Purpling of older leaves.
Solution

Soil/Drip: S Mag 25kg/acre
Benefit: Helps in photosynthesis, starch translocation
Sulphur deficiency
Symptoms: Plant shows stunted, erect growth. Seen from a distance, younger leaves are coloured uniformly pale, but when you look at them closely, it’s rather an intervenial chlorosis.
Affect: Stunted growth.

Benefit: Improves special character in crop
Boron deficiency
Symptoms: Symptoms expressed as shortening of internodal and results in transparent necrotic spots. Lack of boron deficiency will results in smaller cobs.
Affect: Death of growing points.
Solution
Product: S Bore 1gm/1Lt. Of water
Soil/Drip: –
Benefit: Translocation of sugars and help in pollination
Zinc deficiency
Symptoms: White to pale yellow bands in the lower half of the leaf which advance to pale brown or grey necrosis.
Affect: Pale green plants.

Nitrogen deficiency
Symptoms: The leaves turn uniformly pale green colour. The oldest leaves on the bottom show yellow discolouration and subsequent necrosis proceeding from the leaf tip to mid rib.
Affect: Affected plants show stunted, sparse growth.
Solution

Soil/Drip:
Benefit: Quick Action on plant to recover Fungal
Pest in Maize
Symptoms:
- Plants become unhealthy stunted and yellow.
- The leaves wither from top downwards.
- Panicle formation is inhibited and the plants die if attack is severe.
- Honeydew secreted by the bug causes growth of sooty mould on. leaves.
- The midribs of the leaves turn red due to egg-laying and may. dry up subsequently.
Affect: Pest damage the outer cells of the leaf and fruit as they feed on the plant sap.
