Fungal Disease

Disease requires warm and humid climate to establish and spread. A continuous leaf wetness more than 6 hours helps in disease establishment. Warm temperature along with longer hours of leaf wetness helps in disease spread. For primary infection to occur free flowing water, by means of rain splashes is ideal for spores to spread. Prolonged rainfall helps in disease spread.

In disease development high relative humidity plays vital role, irrespective of temperature fluctuations. Keep note of leaf wetness and rainfall days while scouting for the disease.

Cultural controls

• Cover the soil under the plants with mulch, such as fabric, straw, plastic mulch, or dried leaves.
• Water at the base of each plant, using drip irrigation, a soaker hose, or careful hand watering.
• Increase airflow by staking or trellising, removing weeds, and spacing plants adequately apart
• Pruning the bottom leaves can also prevent early blight spores from splashing up from the soil onto leaves. 
• Let two years pass before you plant tomatoes or peppers in the same location.
