The disease causes a white powdery growth on the upper leaves, stems and young growing parts of plants, and as the infection progresses, the entire leaf becomes covered with the fungus. The leaves of infected plants start falling prematurely. If the infection occurs at the fruiting stage, the fruits remain underdeveloped and become malformed.

Control: To control the disease spray, Novacone (Hexaconazole 5% SC) @ 400 ml per acre in 150-200 litres of water as soon as the symptoms appear. Also, take a spray of Nutriful Max (fulvic acid amino acid trace component) @ 250 ml per acre for good flower and fruit development.

Pre-emergence weed management in summer paddy!

In addition to diseases and pests in paddy crops, weeds also cause a lot of damage, so it is very important to destroy weeds in time, as harmful weeds in paddy crops also attract various insects.

Post-emergence weed management:

Post-emergence weed management should be done after 10 to 12 days of transplanting and after weed germination. After the emergence of weeds in paddy crops, spray Nominee Gold (Bispyribac-Sodium 10% SC) @ 80 – 100 ml per acre mixed with 150 – 200 litres of water to control them. Bispyribac-Sodium is a selective, post-emergent herbicide, which controls grasses and broad-leaf weeds in paddy, such as Echinochloa crusgalli, Cyperus difformis, Cyperus iria, Eclipta alba, etc.

Know the reasons for premature tuber sprouting in the main field in garlic crop

Know the reasons for premature tuber sprouting in the main field in garlic crop

Garlic bulbs are sometimes observed to germinate in the field at the beginning of the maturity stage of the bulb, especially when it rains in the winter season or due to excess soil moisture and nitrogen supply. Also, this problem in garlic is caused by irrigation more often than the normal requirement in the crop.

Short-duration varieties are more susceptible to this problem than long-duration varieties. Delayed harvesting in the rainy season leads to premature germination and cracking of tubers. Also, the wide spacing of cloves at the time of planting increases the absorption of nitrogen and water by individual plants, resulting in premature germination.

Damage caused by red pumpkin beetle in watermelon and preventive measures

In this pest, both nymphs and adults damage the crop. The young eat the root, underground stem and fruits attached to the ground, due to which the plant starts withering or rotting may also occur in the plant. Adult insects make holes in the leaves of plants, due to which the plant does not grow and when the outbreak increases, the plant also dies and due to this, there are burnt spots in the field. This pest can also damage the flowering stage, which reduces the fruit set, and in severe stages, production can be reduced by 90%.

Preventive Measures: To control this pest, plough the fields immediately after harvesting and destroy the dormant adults. If infestation is observed, take a spray of Emanova (Emamectin Benzoate 5% SG) @ 100 gm/acre or Tafgor (Dimethoate 30% EC) @ 200 ml per acre in 150-200 litres of water.

It is a seed-borne disease in wheat crops. The symptoms of this disease appear only after the Bali stage. Instead of grains, spores of the pathogen are found in the form of black powder in the ears of diseased plants and these spores are covered with a thin membrane. Affected plants usually mature earlier and have a shorter height.

Preventive measures for loose smut disease:

Seed treatment is the best way to control this disease. Remove infected spikes when leaves turn yellow. Apart from this, spray Carmanova (Carbendazim 12% +  Mancozeb 63%) @ 600 gm/acre or Tesu Nova (Tebuconazole 10% + Sulphur 65% WG) @ 500 gm per acre in 200 litres of water to control the disease.

Identification and control of powdery mildew disease in okra crop

Powdery mildew disease symptoms are clearly visible on both the old leaves and stem of the plant. White-coloured powdery spots are formed on the leaves and stems of the affected plants. As the attack progresses, the leaves turn yellow and start falling off. The fruits of infested plants remain small in size, and the production is also very less due to this. The outbreak of the disease increases when there is more humidity in the environment.

Control: To control it, spray Bavistin (Carbendazim 50% WP) @ 200 grams per acre in 150 to 200 litres of water or Sulphur 80% WP @ 1.2 kg per acre in 300-400 litres of water.
