testing) Indian major carp & Foreign carp can be released in pond @
2000 pieces fingerling. Please maintain the recommended ratio.
Complementary feed must be given regularly. Don’t use excess feed to
avoid water pollution.
For Aphid, hoppers, white fly apply Imidachloropid @1ml/5lit. of water or thiomethoxam @1g/3lit of water. For yellow mite apply propergite 2.5 ml/lt. of water.to control
sucking pest of chilli apply Flubenamide 39.35% SC @ 4 ml/tank. Bacterial wilt control measure same as Brinjal, In case of blight of twigs from the top of the plant need to be sprayed with Difenoconazole 25 EC @ 1ml/lit of water.

days, spray aloe vera with 12.5 g of diafenthuron + 25 ml of
tebuconazole per tank..
BRINJAL
Yellowing of leaf and Fruit drop: Such problems are due to
lack of zinc
nutrients in the soil and whitefly infestation. 1. As the first
spray, spray zinc
EDTA in 1 gram per liter of water. 2. On the second day,
spray 12.5 g of
diafenthuron and 25 ml of eoxystrobin + teboconazole per 15
liters of water. 3.
After seven days, spray Diafenthuron 12 gm in 15 liters of
water. 4. After
seven days, spray zinc EDTA in 1 gm per liter of water. 5. Cut

sprayed with 40 g
of copper oxychloride and 1 g of streotocyclin per 10 liters of
water. 2. After
seven days, the mixture of azoxystrobin + tebuconazole
should be sprayed in 1
ml per liter of water. 3. After seven days, four grams of copper

Undulating Red and Laterite Zone Crop Stage Problem Advisory
RICE Prevailing weather is favorable for an attack of Brown Plant Hopper (BPH) and white
Backed Plant Hopper (WBPH). To manage farmers are directed to follow a spray
schedule with Buprofezin 25% SC@ 0.5 ml/l or Thiamethoxam 25% [email protected] gm/l or

rice. To manage the disease spray Propiconazole or Hexaconazole @ 1 gm/L of water
after the cessation of rain. There may be an attack of yellow stem borer, Case worm,
leaf folder at this stage of kharif rice. Keep vigilance. If severe infestation is observed,
application of Cartap hydrochloride 4G @3.5kg/bigha or Chlorantraniliprole 0.4 GR
@ 1.3 kg/bigha or fipronil 0.3% GR @ 0.7-1 kg/bigha are advised to protect the crop
from these pests.
