Plantation of this plant is thought about to be an outstanding fuel substitute and it is also extremely affordable compared to other fuels. Recently, Jatropha is facing some difficulty with bugs and illness. The insects are classified into 2 ranges: Pest that impact young plants and Pest that affect grown plants.

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

Agrotis ipsilon: It is frequently understood as Cut worm. This bug affects the seedlings and young jatropha curcas plants. If the plant is affected by the cutworm, the stem gets cut nearer to the soil surface and this will shrunk the plant totally.

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

Control: The plant with excellent resistance power can conquer the bug. For heavy attack, insecticides with parts carbosulfan and carbofuran can be used to eliminate the insect.

Army worm: Spodoptera litura presence can be identified by biting in the leaves. The severe infection might entirely eliminate the plants.

Control: Insecticides are utilized to manage the bugs.

Grasshopper: This is typical pest discovered in several plants. Valanga nigricornis and Locusta migratoria widely attacks the plant. The pest frequently assaults the young plant.

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

Pest observed in mature plants:

Pest of Stem: Ostrinia furnacalis, Xyleborus spp.

Ostrinia furnacalis and Xyleborus: This bug harms the jatropha curcas stem and it is extensively seen in Indonesia. The stem attacked by this pest typically fall down. 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 insect can consume all the leaves of the plant in brief period. The quality and yield of the seeds get minimized due to the heavy attack.

Control: This can be controlled by selecting the old larvae around the surface and discarding the attacked leaves.

Needle Caterpillar: This caterpillar is covered with spines and produces a burning feeling when enabled to call with skin as it produces certain chemical compound. Initially the bug crowded in the leaf and after that spread out all over the plant when it ages.

Control: Manually, the pest can be eliminated just by soaking it in water or kerosene. The heavy attack can be managed by spraying organophosphate insecticides.

Leaf Hopper: This insect is found mainly in tropical and subtropical areas. The insect targets the leaf and draws all the nutrients of the leaf and gets curls at the pointer. Later, the entire leaf dry and pass away.

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

Mite: Mite also attacks the leaf and makes the entire plant weak. The pest presence can be recognized when the leaf ended up being yellow-colored, diminishes, reddens and fall down. The insect can also be spread through fallen leaves.

Control: Some preventive steps can be done like proper sanitation and burning the fallen leaves. Heavy attack can be dealt with by spraying insecticides.

Chrysocoris javanus, Tip borer caterpillar.

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

The harmful enzyme in the plant diminishes the entire plant.

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

Tip borer caterpillar: The pests frequently takes place attacks the plant in blooming season and this insect is seen widely in tropical areas. The female pest laid the eggs on the tender part of the plant and the young larvae feed the young fruits and plant suggestions.

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