GROUNDNUT : 

GROUNDNUT IMPORTANT OIL SEED CROP OF A.P AREA OCCUPIED BY THIS CROP IS AROUND 1.7 m.ha. DROUGHT RESISTANT CROP. SHORT DURATION CROP : 110-120 DAYS YIELD POTENTIAL IS 750-1150 Kg / ha. NITROGEN FIXATION BY Rhizobium BACTERIUM THROUGH ROOT NODULES

GROUNDNUT : 

GROUNDNUT IT WILL FIT TO VARIOUS TYPES OF CROPPING SYSTEMS. ENTIRE PLANT IS USEFUL. HIGH DEMAND FOR KERNEL, SEED AND OIL.

MAJOR PROBLEMS OF GROUNDNUT CULTIVATION UNDER RAINFED CONDITIONS : 

MAJOR PROBLEMS OF GROUNDNUT CULTIVATION UNDER RAINFED CONDITIONS ERRATIC RAINFALL. INSECT PESTS – ROOT GRUB, RED HAIRY CATERPILLAR, TOBACCO CATERPILLAR, THRIPS AND JASSIDS. DISEASES – EARLY LEAF SPOT , LATE LEAF SPOT AND ROOT ROT. VIRUSES –PEANUT STEM NECROSIS VIRUS.

RED HAIRY CATERPILLAR : 

RED HAIRY CATERPILLAR PHYLUM – ARTHROPODA SUB PHYLUM – MANDIBULATA DIVISION – PTERYGOTA CLASS – INSECTA FAMILY – ARCTIIDAE GENUS – AMSACTA SPECIES – ALBISTRIGA, LACTENIA, LINEOLA , MOOREI.

BIO – ECOLOGY OF RED HAIRY CATERPILLER : 

BIO – ECOLOGY OF RED HAIRY CATERPILLER

ADULT EMERGENCE : 

ADULT EMERGENCE Down pour during summer followed by soaking rainfall of more than 25 mm. 24 hours after soaking rainfall i.E night during 7.00 – 11.30 pm. Average temperature of 30˚c and minimum humidity of 65%.

ADULT BEHAVIOUR : 

ADULT BEHAVIOUR Female live for maximum five days. Male live for two days. Adult lay eggs in clusters. Egg laying ranging from few hundreds to two thousands. Sites of egg laying : under surface of the leaves, base of the stem, stones, devices of light trap etc.,

ADULT BEHAVIOUR : 

ADULT BEHAVIOUR Adult prefers to lay eggs on leaves of shrubby and succulent weeds. Adult prefers to lay eggs on weeds of the bund and boarder crops. Eggs hatch after 24 hours of laying.

LARVAL BEHAVIOUR : 

LARVAL BEHAVIOUR I & II instar larvae prefers to feed young and succulent foliage of crop and weed plants. I & II instar larvae prefers cowpea, field bean and redgram as intercrop or boarder crops. III & IV instar larvae prefers medium sized leaves, young branches, floral parts ( sepals, petals and gynophore )etc.,

MANAGEMENT OF RED HAIRYCATERPILLAR : 

MANAGEMENT OF RED HAIRYCATERPILLAR

I. ADOPTION OF SUITABLE CROPPING SYSTEM : 

I. ADOPTION OF SUITABLE CROPPING SYSTEM Sowing one / two rows of sorghum as boarder crop. Sowing three rows of cowpea as trap crop next to sorghum.

II.PEST SURVEILLANCE : 

II.PEST SURVEILLANCE Setting of light traps at the rate of one per 10 ha at 24 hours after every soaking rain since sowing to 100 days of crop stage. Collection and destruction of adults and egg masses around light traps, weeds on bunds, boarder crop, trap crop and main crop.

II.PEST SURVEILLANCE : 

II.PEST SURVEILLANCE Arrest of migration by digging pit around field bunds and dust with folidol. Dusting of Folidol ( methyl parathion – 2 % ) on field bunds, boarder crop and trap crops.

II.PEST SURVEILLANCE : 

II.PEST SURVEILLANCE Walking with a close watch and trmpling the larvae under feet atleast once in a week. Dust folidol in the pit / boarder crop / trap crops based on the need.

III.CHEMICAL INTERVENTION : 

III.CHEMICAL INTERVENTION If number of larvae exceed 30 / m² , dusting folidol / ekalux / endosulfan on the crop starting from the boarder to the centre of the field. Poison bait with nuvan / ekalux at the rate of 1l + 1kg jaggery + 5kgrice bran and keep small pellets at base of the plant.

III.CHEMICAL INTERVENTION : 

III.CHEMICAL INTERVENTION Spraying on the crop during morning or evening with Quinalphos at the rate of 2.5 ml or Nuvan at the rate of 1.5 ml per litre of water.

FACTORS AFFECTING THE SUCCESS OF CHEMICAL CONTROL : 

FACTORS AFFECTING THE SUCCESS OF CHEMICAL CONTROL Larval stage should be i , ii , iii & iv. Arrest of immigration and emigration of larvae before and after chemical application. Crop should be destrubed before chemical application. Dosage should be optimum.
