Recently, Jatropha is facing some trouble with pests and illness. The pests are classified into 2 varieties: Pest that impact young plants and Pest that affect developed plants.

Young plant bugs: Cutworm, Scarabeid Beetle, Army worm, Grasshopper.

Agrotis ipsilon: It is commonly called Cut worm. This pest affects the seedlings and young Jatropha plants. If the plant is impacted by the cutworm, the stem gets cut nearer to the soil surface and this will shrunk the plant completely.

Control: This bug can be managed by selecting the larva found around the plants or by blending the bran, sawdust with insecticides.

Control: Insecticides are utilized to control the pests.

Grasshopper: This is common bug found in numerous plants. Valanga nigricornis and Locusta migratoria commonly attacks the plant. The insect typically assaults the young plant.

Control: The insecticides used betacyfluthrin, cypermethrin, thiodicarb, MIPC, and fipronil.

Pest observed in mature plants:

Pest of Stem: Ostrinia furnacalis, Xyleborus spp.

Ostrinia furnacalis and Xyleborus: This insect harms the Jatropha stem and it is widely seen in . The stem attacked by this insect generally drop. The presence can be identified by the larva penetration hole at the stem.

Control: The Insecticide generally used to control this insect is carbofuran.

Pest of leaf: The common pests observed are leaf caterpillar, Neetle caterpillar, Leaf hopper, Mite, Ear corn caterpillar.

Leaf Caterpillar: This bug can consume all the leaves of the plant in other words duration. The quality and yield of the seeds get lowered due to the heavy attack.

Control: This can be managed by picking the old larvae around the surface and throwing away the attacked leaves.

Needle Caterpillar: This caterpillar is covered with spines and produces a burning feeling when allowed to call with skin as it produces specific chemical substance. Initially the bug crowded in the leaf and then spread out all over the plant when it grows older.

Leaf Hopper: This pest is discovered mainly in tropical and subtropical regions. The insect targets the leaf and draws all the nutrients of the leaf and gets curls at the suggestion. Later, the entire leaf dry and die.

Control: The heavy attack can be controlled by using insecticides like imidachloprid, beta cyfluthrin or carbosulfan.

Mite: Mite also assaults the leaf and makes the whole plant weak. The bug presence can be determined when the leaf ended up being yellow-colored, diminishes, turns red and drop. The bug can also be spread out through fallen leaves.

Control: Some preventive procedures can be simulated correct sanitation and burning the fallen leaves. Heavy attack can be treated by spraying insecticides.

Stink Bug: Sting bug is a major pest which assaults the plant throughout blossom duration so the crop yield entirely falls down. This bug is seen around the tropical region.

The poisonous enzyme in the plant diminishes the entire plant.

Control: Insecticides recommended for this bug is chlorfluazuron, diflubenzuron, alfamethrin, and lamda cyhalothrin.

Tip borer caterpillar: The pests commonly happens attacks the plant in flowering season and this insect is seen commonly in tropical regions. The female bug laid the eggs on the tender part of the plant and the young larvae feed the young fruits and plant ideas.

Control: Manually, the attacked seeds are suggested to burn. The insecticides like monocrotophos and bensultap are sprayed at the blooming season.
