Control of Blight in Maize

21/01/2019Posted on

Corn leaf blight is a fungal disease of maize caused by the plant pathogen Bipolaris maydis. Initially small, water-soaked spots appear on leaves, then elliptical brown areas develop until nearly as wide as the leaf. In the final stages, lesions are straw-coloured to grey, coalescing and killing large parts of the leaves.

Control:-

  • Crop rotation to reduce previous corn residues and disease inoculum.
  • Tillage to help break down crop debris and reduce inoculum load.
  • Avoid repeated use of fungicides with the same active ingredient.
  • Spray Mancozeb 75% WP 400 gm/acre or Metalaxyl 35% WS 150 gm/acre.

  • Central shoot withers and leading to “dead heart”.
  • Larvae mines the midrib enter the stem and feeds on the internal tissues.
  • Boreholes visible on the stem near the nodes.
  • Young larva crawls and feeds on tender folded leaves causing typical “shot hole” symptom.
  • Affected parts of the stem may show internally tunneling caterpillars.
  • In later stage, plant becomes die.

Control

 

  • Mix any one of the following granular insecticides with sand to make up a total quantity of 50 kg and apply in the leaf whorls on the 20th day after sowing.
    Phorate 10% G 4 kg/acre or Fipronil 0.3% G 5 kg/acre on 15-20 day after sowing.
  • If granular insecticides are not used, spray any one of the following:
    • Bifenthrin 10% EC @ 200 ml /acre on the 20th day of sowing.

Damage:-

  • Fall armyworm generally feeds on foliage, but during heavy infestations, larvae will also feed on corn ears.

  • They will frequently be near the tip but may feed down the ear creating a track of damaged kernels.

Control:-

  • Set up of light traps.
  • Set up sex pheromone traps at 5 /Acre.
  • Apply any one of the following on presence of pest.
  • Emamectin benzoate 5% SG @ 100 Gm per acre.
  • Fipronil 5% SC @ 400 ml per acre.
