Integrated Pest and Disease Management in Peas Crop
Aphids: Both nymphs and adults of this insect harm by sucking the juice from soft parts of plants. After the attack of this insect, black spots are formed on the leaves, which has an effect on plant growth and yield.
Management: 1. Break the stem or other parts of the plant where the aphids are apparent. 2. Spray neem oil 1500 ppm 1 litre per acre dissolved in 200 litres of water and spray it at 10 days interval. 3. In case of additional outbreak, Thiamethoxam 25% WG @ 40gm/acre should be sprayed by dissolving in 200 litres of water. Leaf Miner: This insect is more harmful during plant growth stage. The maggot of this insect makes a tunnel in the leaves and destroys by eating green parts of the leaves. Management: 1. Spraying of 4% neem kernel powder (40 grams neem kernel powder per litre of water) has been found beneficial for control of this pest. 2. In case of more outbreaks, Imidacloprid 17.8 % SL @ should be sprayed at 40 ml per acre with 200 litres of water or Thiamethoxam 25% WG @ 40 gm per acre at 200 litres at 10 to 15 days interval. Major Pea Disease Powdery Mildew Disease: Stem, leaves and pods are affected by this disease. Mild stains are formed on the affected areas, which later grow into white powder and merge with each other and gradually the whole leaf and plant are covered with white powder and later the leaves fall off. Management: 1. Select Resistant varieties. 2. At the beginning of the outbreak, spray Sulphur 80% WG @ 500 gm per acre in 200 litres of water. Wilt: This is a fungal disease in peas. The affected leaves turn yellow and the plant dries up. Management: 1. For the prevention of crop disease, the seed should be sown before treatment with Thiram 2 gram + Carbendazim 1 gram per kg seed or Trichoderma 4 gram + Betavax 2 gram kg 2. One should choose varieties resistant to disease. 3. For prevention of disease in standing crop, Carbendazim 50% WP @ gm/acre in should be dissolved in 200 litres of water in the soil in the root zone. Source: AgroStar Agronomy Centre of Excellence
