AGRO METEOROLOGICAL ADVISORY FOR West Godavari DISTRICT,

Transplanted rice
 Present weather conditions are favourable to increase rat population and cause the damage to
rice, hence rat traps @ 20 per acre may be arranged in the standing fields
there
by
manage the rat population.



Under present weather conditions stem borer on rice may attach, if the problem is
serious this can be managed by spraying with cartophydrochloride @2 grams or
chlorostriniprole @ 0.4 ml/ per litre of water
Due to present high temperature coupled with rains and humidity may causes bacterial
attach on rice these bacteria leads leaf drying from margins then turn to drying. This
can spread through the irrigation water. chemicals are not available for managing this
disease. Only way is to manage the nitrogen application. If intensity is more than 5 %
stopped the N application
The present weather condition leaf folding is happens it was controlled using of
cloriphiriphas 2.5 ml or esiphate 1.5 gra or cartaf hidrocloride 2 gra. Clorastraniliprole
0.4 ml or phlobimdamide 20 wpg 0.25 gra or 48 s.c 0.1 ml spry with one liter water.
Direct seeded Rice





Rains during last week enhance weeds and are become major problem in direct seeded rice,
hence apply namini gold 80-100 ml per acre in 200 liters of water
Present weather congenial to top dress chemical fertilizers to direct seeded rice crop. Hence
apply chemical fertilizer without loose the moisture
Present weather conditions are favourable to increase rat population and causes the damage to
rice hence rat traps @ 20 per acre may be arranged in the standing fields
Under present weather conditions stem borer on rice may attach, if the problem is
serious this can be managed by spraying with cartophydrochloride @2 grams or
chlorostriniprole @ 0.4 ml/ per litre of water
The present weather condition leaf folding is happens it was controlled using of
cloriphiriphas 2.5 ml or esiphate 1.5 gra or cartaf hidrocloride 2 gra. Clorastraniliprole
0.4 ml or phlobimdamide 20 wpg 0.25 gra or 48 s.c 0.1 ml spry with one liter water.
Maize








Presently received rains henhence the incidence of tarsicum blight and rust on maize due to
excess moisture these diseases can be managed by spraying with 500 grams mecozeb by mixing
with 200 leters of water in the evening.
Presently received rains are useful for recovery of crop from present dry weather condition and
also for top dressing of chemical fertilizers. Still time is there for taking the Kharif sowings, hence
farmers are advised to for Kharif maize sowings as the situation is favourable for taking the
sowings
Suggested verities for the district are DCH-111, DCH-113, DCH-115, Maandhuri &
Priya (sweet verities)
Before sowing seed treatment should be follow
Present rains wash out the sucking complex, need not go for spraying against sucking pests but
stem borer may be the problem. This can be managed by placing the trichograma nicholus 2-3
egg sheets per acre or spray chlorontriniliprol @ 60 ml per acre in 200 liters of water or if the
problem is severe apply prorate or thimmate grannels 3-4 kg per acre by mixing with sand and
placed in whorls.
Present rains are useful for topdressing of urea fertilizers. To overcome present moisture problem
adopt inter cultivation with gorru will improve the growth and reduces the weeds. But
intercultivation may not be possible due to moisture, apply 2-4D @ 500 grams/acre will reduce
the weeds
Under present dry weather condition sucking pest may attack in pegion pie but these sucking pest
naturally controlled by lady bird beetle and spiders. If it is above thresh level it can be managed
by monocrotophas 320 ml or diemithoyote 400 ml deslove 200 liters of water may spry in the
evening times.
Blackgram






Under present weather conditions ie, last received rains may wash out the sucking complex.
But these sucking pests are very serious on the seedlings this can be managed by spraying
with acephate @ 1gr. or monichrotophos @ 1.2 ml per litre of water during morning or
evening time.
Adopt intercultivation if crop is at 30-40 days this will helps in reduction of weeds as well as
aeration to the crop
Present weather henhence the stem fly infestation, it can be managed by spraying 1.6 ml
monochrotophos or 1 gram acephate or 1.5 ml dimethiate per liter of water
Present weather is favourable for Spodoptera this can be managed by spraying 1.6 ml
monochrotophos or 1 gram acephate or 2.0 ml quinalphos + 1.0 dichlorwas per liter of water.
If intensity is more go for spraying of spinsad or 0.3 ml or amomiktin benzoate or 0.4 gram
renoxyphir or 0.2 ml flubendimyde per liter of water
Under present weather situation white fly and sucking pests population may be reduced
there by mosoic virus infestation may not be serious why because these pests washed
out by the present rains hence no need to go for control measures.
Late sown blackgram may prone to iron deficiency due to this rains . this can be
managed by application iron sulphate and citric acid on the crop
Greengram
 Under present weather conditions ie, last received rains may wash out the sucking complex.

 Present weather henhence the stem fly infestation, it can be managed by spraying 1.6 ml

 Present weather is favourable for Spodoptera this can be managed by spraying 1.6 ml
monochrotophos or 1 gram acephate or 2.0 ml quinalphos + 1.0 dichlorwas per liter of water.
If intensity is more go for spraying of spinsad or 0.3 ml or amomiktin benzoate or 0.4 gram
renoxyphir or 0.2 ml flubendimyde per liter of water
 Under present weather situation white fly and sucking pests population may be reduced
there by mosoic virus infestation may not be serious why because these pests washed

 Late sown blackgram may prone to iron deficiency due to this rains . this can be
managed by application iron sulphate and citric acid on the crop
Sugarcane:

Due to rains during last few days the sucking pests may reduced due, hence farmers are advised
do not go for chemical control of sucking pests on sugarcane but presently temperatures are
slightly increased and rains intensity also reduced, hence there is a possibility of increasing the
infestasion


Apply top dressing of chemical fertilizers by using the present moisture
Due to rains fields may be over saturated and leads to drainage, hence farmers are advised to drain
out the water by making field drainage channels
If crop is yet to be harvested under inundated or over saturated conditions, farmers are advised to
remove the water and go for harvesting of cane immediately after drained out the water
Under over saturated conditions there is a possibility of attaching the oogy fly. For management
of this fly apply 3ml of malathion or 1.7 ml of dimethiote per litre of water



Under present weather i.e., medium rains coupled with moderate winds causes cane lodging,
hence farmers are advised to go for waffling and proofing of the cane stalks. ---------------------
