• Grape is an important fruit in India, which have a high export

potential.

• Grapes are mostly used for table purpose, wine and raisin

making.

• Grape vine is attacked by various insect pests like Leafhopper,

Thrips, Leaf-roller, Flea beetle etc.

Introduction

Nature of Damage:

• Adults and nymphs of leaf hoppers suck

cell-sap from lower surface of leaves.

• Affected foliage shows tiny white spots.

• Grape leaves turn yellow-brown and fall.

• Photosynthesis activity is affected,

reducing quality of nursery seedlings.

Control:

• Spray 2.5 ml Fenitrothion 50 EC in 10

liters of water after monsoon.

Host Plants: Grape, Rose, Jamun

Nature of Damage:

• Affected leaves turns white, withered and then turn brown.

• Leaves subsequently curl up and drop off.

• Seedlings show poor vegetative growth.

Control:

• Remove infested leaves from plant.

• Spray 5 ml Malathion 50 EC in10 liters water.

Thrips: Rhipiphorothrips cruentatus

Adult Thrips

Nature of Damage:

• Young, green caterpillars (1-3 instars) feed

on lower epidermis of leaves, reducing

them to leaf skeletons.

• Mature larvae (4th 5th instars) roll up the leaf

margins towards mid-rib and pupate in the

leaf roll.

Control:

• Remove the leaf rolls and destroy them.

• Spray 5 ml Malathion 50 EC in 10 liters

water.

Nature of Damage:

• Grub feeds on cortical portion of roots.

• Adults are more destructive as they feed voraciously on new buds turning them into 'dried sprout'.

• Later it causes longitudinal slits on the lamina of the leaves.

Control:

• At early bud sprout spray 0.05% Quinalphos by mixing in water

Flea beetle: Sclelodonta strigicollis

White grub or root grub is the immature stage of Scarab beetles

popularly known as cock chafers, leaf chafer, chafer beetle, May

beetle or June beetle.

Host Plants

•White Grub is a polyphagus pest

and feed on almost all kharif season crops.

•It is widely seen in groundnut crop

and chilies of sandy loam soil.

•White Grub are mainly observed

during rainy season in nursery.

Nature of Damage

• The white grub and adult feeds on the living roots and later adults

feeds on shrubs and the trees like neem, khejri etc. growing near

the nursery fields.

• The young grubs after hatching in the soil headed towards the

roots and start feeding on them.

• Consequent to feeding, the plants

show varying degree of yellowing,

some get wilted and ultimately die.

Such affected plants easily collapse.

Control:

• Collect and destruct beetles in kerosene mixed water and

using light traps / pheromone traps during night hours. Spray

0.0 % Carbaryl on the host plants.

• Deep ploughing of field is a good practice.

• Pre-sowing soil treatment with Phorate 10G or Quinalphos 5G

or Carbofuran 3G @ 300 gm / gunta.

• Application of Quinalphos or Chlorpyriphos at 400 ml / gunta

with irrigation water.

• Bio-control: Pathogenic nematode infecting white grub.

Host Plants

• Polyphagus pest of all nursery plants.

Nature of Damage

• In loamy and light soils in dry areas where proper facilities for

irrigation are not available, the termite infestation is more serious.

The infestation of termite is more in rabbi season.

• Termites feed on cellulose in the roots of seedling. As a result of

infestation, the leaves get dry and seedling can easily be pulled

out. In later stage the whole seedling withers.

Control

• Use of well decomposed organic

manure. Remove dead and

decaying organic matter or dry stubbles

from field to avoid termite

infestation.

• Irrigation protects the plants from termites.

• Treat soil with Quinalphos 1.5 % or methyl parathion 2 % dust @

0.25 kg / gunta before planting .

• Apply Chlorpyriphos 20EC @ 400 ml / gunta with irrigation water.
