Chillies diseases and their control

Chillies diseases are the same as those found on tomatoes, peppers and brinjals. The reason is that they are all from the same family of crops. Most small scale farmers do not have the necessary industrial spray equipment to control chilli diseases effectively but that is no reason that hand sprays do not work. Hand sprays and back sprays are affordable and cheap to maintain and careful application of chemicals can offer just as good control. What is important is when walking through the crop one should look carefully where you spray so any other disease is also noticed. It is often found that the more one walks and scouts the more effective disease control becomes.

Powdery mildew (White rust)

  • Disease: It is caused by the fungus Oidiopsis taurica and is especially present during warm, humid conditions. The disease can affect the plant significantly and cause total leaf loss.
  • Control: Use vine sulphur or wettable sulphur when the first disease symptoms are noticed or spray weekly with Benlate.

Bacterial Spot

  • Disease: Cause by Xanthomonas vesicatoria and is noticable as small brown spots on the leaves
  • Control: Apply chemicals as soon as the first sign of the disease appears. Because the leaves fall of easily as a result. Spray with any chemical that contains copper oxychloride and Zineb (64% copper oxychloride and 20% Zineb). The mixture must be used immediately and not left overnight in the spraying tank

Bacterial wilt

  • Disease: It is caused by the organism Pseudomonas solanacearum. At the moment there is no practical control method
  • Control: No control method yet. The best practice is to stop activities that spreads any disease throughout the  farm. Limit the spread of dead plant material. Wash gloves. Limit movement between fields. Do not let representatives walk around the farm with their own boots. Give them boots to wear from the farm. They must also wash their hands when entering the farm.

Sclerotium wilt

  • Disease: It is caused by the fungus Sclerotium rolfsii. There is no chemical control for this disease.
  • Control: Again limit activities that help the spread of fungi and diseases on the farm
