In order to utilise the rainfall during monsoon season, all the relevant agricultural activities may be carried out successfully. Based on the realized weather parameters during last few days and weather forecast for next five days, following agromet advisories are issued.

Aus

• Maintain in 3-4inches water level at recovery stage.
• Inspect & monitor  disease-pest e.g blast, rice bug, stem borers and others and take appropriate plant protection measures.
•  Apply potash fertilizer as top dress by filling gap after 5-7 days and also urea fertilizer after 3-5 days. Urea fertilizer should not be applied if the paddy is in early tillering stage. After 5-7 days, if necessary, urea fertilizer should be applied by breaking the tillers and filling the gap. At this time, it is better to use additional 5 kg of potash fertilizer per bigha in all types of aus paddy fields.
• If the population of Thrips and Green Leaf Hopper exceeds 25%, apply Malathion group insecticide at the rate of 1ml/1 litre of water.

Aman Paddy

• Advise for preparation of seeded for Aman paddy in kharif season.
• Start sowing of dry seeded long duration paddy after proper tillage operation like ploughing, weeding etc.
• Before sowing seed should be treated by Diethane M-45 properly
• Farmers are advised to practice Dapog method for raising nursery bed.

Groundnut

• Harvest the matured crop on non rainy days.
• Monitor the incidences of pests (hairy caterpillar, jassid, thrips, leaf miner, spodoptera & termite) & diseases (leaf spot/tikka disease, leaf rust, foot rot/stem rot, collar rot, bud necrosis) and if noticed, take appropriate preventive measure.

• Prevailing weather condition are favorable for tikka leafspot in groundnut. To control spray with hexaconazol @2ml. or carbendazim @1 g. per litre of water.

Vegetables

• Hand pollination is effective for more production in case of tassel gourd and pointed gourd. Advised to cut aged leaves and continue others intercultural operations in vegetables land.
• Wash away sticky mud from base and stems of vegetable plants by spraying fresh water; to prevent rotting, spray Copper hydroxide or copper oxychloride@4g per litre of water. Staking of bamboo should be provided to crops like tomato, chilli and brinjal for better support.
• Arrange for adequate drainage to avoid water stagnation in the crop fields. Drain out excess water from the fields. Avoid irrigation, intercultural operation and application of plant protection measures and fertilizers to the standing crops. Harvest the matured crop immediately and store the harvested products at safe places.

Horticulture

• Weather is congenial for sigatoka leaf spot disease in banana; cut and remove all severely affected leaves and spray Propiconazol 1ml/ litre of water. Weather is congenial for burrowing nematode in banana; apply neem cake (1 kg/plant) at the time of planting to reduce the pest population. Store the harvested banana bunches in dry places to prevent disease incidence due to rainfall.
• Provide mechanical support to banana, young fruit plants and vegetables and carry out propping up in sugarcane to prevent the crops from lodging due to strong winds. Keep harvested produce at safer places. Keep cattle/goats indoor during thunderstorm/dust storm.
• Weather is congenial for bud rot disease in coconut; spray 1% Bordeaux mixture on the spindle leaf and crown of palms. Make provisions for small drains at required interval in the orchards to drain out excess water.

Jute:

• Keep the jute land weed free by weeding and uproot comparatively under growth plant during the time.
•  There is a chance of incidences of Semiloper. Spray Imidocholoprid/Chlorocyrin/ Nitro @ 1ml/litre of water. Semilooper and mites may be infested in drought and humid weather and so placing 10-12 bamboo sticks/ plant branch @33 decimal land for controlling insects as environment friendly way. Besides, inspect the land regularly.
• To protect capsularis jute crop (>4 ft tall) from lodging due high wind speed, the peripheral jute plants (round the field) need to be tied together by taking 4-5 jute plants in a consecutive manner.

• There is a chance of incidences of Hairy Caterpillar. Following control measures is advised.

• Collect the egg mass and destroy

• Use light traps.
• Spray Imidocholoprid/Chlorocyrin/ Nitro @ 1ml/litre of water.

Betel vine:

• At Leaf growing stage the fencing and structure of betel vine garden broken due to “strong wind. Repair the structure as early as possible and if required took down the creeper from the structure.
• Wet the plant and the base soil with copper oxychloride solution --Spray 1% Bordeaux mixture at the base.
• Intercultural operations need to continude as others month.
• Hail storm and western storm may be possible at this time, so special care should be given for beetle leaves.

Livestock

• During the month, cattle vaccination need to be provided for controlling Anthrax and HS (Hemorrhagic septicemia) disease (not disease cattle). In this time, mosquito infestation may increase and advised for arranging curtain. Regular bathing the cattle while increasing hot weather.
• Provide supplemental feed of minerals and vitamin mixture farm animals; carry out proper deworming schedule and vaccination schedule against FMD.
• Keep the cattle under shed during heavy rainfall. Keep the animals in dry and high (raised platform) places. Take proper care of the shelters and look out for any possible outbreak of diseases of livestock. Do not let the animals outside during thundershower. Avoid water logging of floor of the animal house.
