Symptome

In the ear head, a pink to red liquid is secreted from the infected florets. It can drop on the foliage and onto the ground. The liquid contains a large amount of conidia. Infected florets do not produce grains. Black fungal masses replace the seeds.

Auslöser

Favorable conditions are a relative humid climate and temperatures between 20 to 39°C. 5 to 7 days after infection, honeydew is secreted. The honeydew promotes a secondary infection of the florets. Ergot can lead to severe health problems for humans and animals in case of consumption. The fungus survives throughout the year in plant residues.

Biologische Behandlung

Crude Neem products can be used.

Chemische Behandlung

Fungicides containing Ziram or Carbendazim can be used to control and prevent Ergot.

Präventive Maßnahmen

    Plant resistant varietiesUse uncontaminated seedsEnsure balanced nutrient supply (low nitrogen and high phosphor)Plant early in rainfed conditionsPlough deep to bury all plant residuesIntersperse Sorghum with Mung bean
