Measures for the prevention of white grub in cotton

Measures for the prevention of white grub in cotton

These insects, which live in the soil during the day, are more active during the night. The larvae of this pest damage the plants by feeding on the roots. Due to the damage to the roots, the plants do not get the proper amount of nutrients. Due to this the plants start drying up and get destroyed after some time.

Control:

  • If this insect is seen, then irrigate in sufficient quantity, so that the insect comes out of the soil when there is moisture in the field.

  • Do deep ploughing immediately after harvesting, due to which the insects hiding inside the ground are destroyed by the heat of the sun and the outbreak of pests and diseases on the crops is reduced. At the same time, the ability of the fields to hold rainwater also increases, which protects the crops from drought.

  • To control this pest, use Fury (Carbofuran 3% CG) at the rate of 4 kg/Acre.

Problem of Nematode in vegetable crops and their prevention

Problem of Nematode in vegetable crops and their prevention

Nematodes are microscopic worm-like insects that mainly attack the plant roots of vegetable crops like – (Tomato, Brinjal, Chili, Okra, and Cucumber). The formation of knots on the roots is the main symptom of this nematode. Small knots are formed on the roots of the diseased plant, due to which the plant’s ability to absorb nutrients and water decreases, due to which the plant remains yellow and small. The growth of the plant stops and eventually, the whole crop dries up.

Control measures:

After light irrigation of the field in summer, do 2-3 deep ploughing at an interval of 10-12 days. Due to this, the nematodes will come to the upper surface and die due to sunlight.

To control it, apply Nemato Free Plus (Verticillium chlamydosporium) @ 2-4 kg/acre at the time of field preparation, sowing or transplanting. Treat the land with Velam Prime (Fluopyram 34.48% SC) 250 ml/acre through drip or drenching.

Identification and prevention of anthracnose disease in moong crops

Identification and prevention of anthracnose disease in moong crops

Both the productivity and quality of the crop are affected due to this disease. Spots are visible on diseased pods. These spots are light brown and red in colour. Similar spots are formed on leaves and stem. It spreads rapidly in the crop when there is high moisture. Circular sickle-shaped spots appear on the pods and the diseased parts fall off. The quality of the seeds affected by this disease gets spoiled.

Control measures:

  • Before sowing, seed treatment should be done with Dhanustine (Carbendazim 50% WP) at the rate of 2 gm/kg of seed.

  • Spray Dhanustine (Carbendazim 50% WP) 100 gm/acre or M-45 (Mancozeb 70% WP) 400 gm/acre mixed with 200 litres of water as soon as the symptoms of the disease are seen in the crop, should be repeated at an interval of 10-15 days as per the requirement.

Identification and prevention of Boron element deficiency in Cauliflower

Identification and prevention of Boron element deficiency in Cauliflower

Boron plays an important role in vegetables. Boron deficiency in cauliflower causes browning of the upper surface of the flower. Boron deficiency symptoms usually appear after flowering. Water-soaked areas appear initially on the stem and flower

Browning disease is caused by the deficiency of Boron. In this, the stem becomes hollow and the flower becomes brown.

To prevent this, mix Calbor at the rate of 5 kg per acre in the soil and spray Boron at the rate of 15 grams per 15 liters of water.

Measures to control fruit borer and stem borer in Brinjal crop

Measures to control fruit borer and stem borer in Brinjal crop

The outbreak of this pest is highest in Brinjal. In the initial stage, its caterpillar makes a hole in the soft stem, due to which the stem and top part of the plant dry up. Due to its attack, flowers fall before flowering. After this, it makes a hole in the fruit and enters inside and eats the pulp. Due to this the affected fruits rot and the fruits are not edible, due to which there is a considerable drop in the market price.

Control Measures: To control it, spray Spintor (Spinosad 45% SC) 75 ml/acre or Fame (Flubendiamide 39.35% SC) 50 ml/acre or Cover (Chlorantraniliprole 18.% SC) 60ml/acre mixed in 200 litres of water.

Identification and control Measures of Damping Off Disease in Chilli Nursery

Damping Off Disease in Chilli Nursery

Damping Off disease spreads through fungus and the outbreak of this disease is mostly seen in nurseries. Most of the effects of Damping Off disease are seen in 10-15 day-old plants. Due to Damping Off disease, the roots and stems of the plants start rotting. The stems of the plants begin to thin and the leaves begin to wither. When plants are removed in large quantities at the time of transplanting, the disease spreads more rapidly.

Control Measures:

  • To avoid this disease, adopt crop rotation and select varieties resistant to damping off disease.

  • Seed treatment before sowing is very important.

  • For biological control, treat Combat (Trichoderma viride) 8g/kg of seed.

  • or  Vitavex (Carboxin 37.5% + Thiram 37.5% WS) @ 3 g/kg or Dhanustin (Carbendazim 50% WP) @ 3 g/kg of seed.

Problem and solution of Rust in Moong Crop

Problem and solution of Rust in Moong Crop
  • The symptoms of this disease are reddish-brown spots appearing on the lower surface of the leaves.

  • These spots are less visible on pods and stems but more visible on leaves.

  • Pods affected by this disease mature early due to which the grains are shrivelled and there is a huge reduction in yield.

  • To control it, spray M-45 (Mancozeb 75% WP) at the rate of 600-800 gm/acre mixed with 200 liters of water.

How to manage weed in cotton

How to manage weed in cotton
  • Weeds are the main problem in the cotton crop due to which the yield decreases. The cotton field should be weed-free for 50-60 days from sowing.

  • It is essential for good yield. Remove weeds by hand before first irrigation or sowing. Also, repeat this process after every irrigation. 

  • Use herbicide within three days of sowing, for this spray Dost (Pendimethalin 30% EC) at the rate of 1000 ml/acre.

  • Sufficient moisture should be present in the soil at the time of herbicide application. By its use, the crop remains weed-free for 40 days.

  • If herbicide was not used at the time of sowing, do weeding between 18 to 20 days after sowing.

  • Use a flat fan nozzle to spray herbicide.

Problem and solution of Damping Off in Cotton Crop

Problem and solution of Damping Off in Cotton Crop

Damping off disease is one of the few fatal diseases affecting the cotton crop. 5 to 20% of crops are destroyed by this disease. The effect of Damping Off disease is more visible in 10-15 days old plants. Due to damping off disease, the roots and stems of the plants start rotting. The stems of the plants begin to thin out and the leaves begin to wither. When the problem of this disease increases, the leaves of the plants turn yellow, start drying up and the plants fall to the ground.

Methods of controlling Damping Off disease:

  • To prevent this disease, adopt crop rotation and select varieties resistant to damping off.

  • Seed treatment before sowing is very important.

  • For biological control, treat the seed with Trichoderma viride @ 8 gm/kg.

  • Treat with Vitavex (Carboxin 37.5% + Thiram 37.5% WS) @ 3 g/kg of seed.

Identification and control of Cercospora leaf spot Disease in moong crop

Identification and control of Cercospora leaf spot Disease in moong crop

Cercospora leaf spot disease causes dark brown spots on leaves with dark to reddish brown outer margins. These spots are more clearly visible on the upper surface of the leaf. Infection of the disease starts from old leaves. Under favourable conditions, these spots become large in size and eventually, the diseased leaves fall.

Control: To control this, treat the seeds with a fungicide called Captan or Thiram (at the rate of 2.5 gm/kg) before sowing or if the Disease appears 10-15 days after sowing, then we should mix Dhanustin (Carbendazim 50% WP) at 200 gm/Acre or M-45 (Mancozeb 75% WP) 400 gm/acre at the beginning and after 10 days of the disease appearance.
