Plantation of this plant is thought about to be an excellent fuel substitute and it is likewise very cost-effective compared to other fuels. Recently, Jatropha is facing some difficulty with pests and diseases. The pests are classified into 2 varieties: Pest that affect young plants and Pest that impact matured plants.

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

Agrotis ipsilon: It is commonly understood as Cut worm. This pest impacts the seedlings and young Jatropha plants. If the plant is impacted by the cutworm, the stem gets cut nearer to the soil surface area and this will diminished the plant entirely.

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

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

Army worm: Spodoptera litura existence can be recognized by biting in the leaves. The severe infection could entirely eliminate the plants.

Control: Insecticides are utilized to control the bugs.

Grasshopper: This is typical insect found in numerous plants. Valanga nigricornis and Locusta migratoria widely attacks the plant. The insect often assaults the young plant.

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

Pest observed in fully grown plants:

Pest of Stem: Ostrinia furnacalis, Xyleborus spp.

Ostrinia furnacalis and Xyleborus: This pest damages the Jatropha stem and it is commonly seen in Indonesia. The stem assaulted by this insect normally fall down. The existence can be determined by the larva penetration hole at the stem.

Control: The Insecticide typically used to control this pest is carbofuran.

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

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

Control: This can be controlled by choosing the old larvae around the surface area and throwing away the assaulted leaves.

Needle Caterpillar: This caterpillar is covered with spines and produces a burning experience when permitted to exposure to skin as it produces particular chemical substance. Initially the bug crowded in the leaf and after that spread all over the plant when it grows older.

Control: Manually, the bug can be killed only by soaking it in water or kerosene. The heavy attack can be managed by spraying organophosphate insecticides.

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

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

Mite: Mite also attacks the leaf and makes the entire plant weak. The insect presence can be recognized when the leaf ended up being yellow-colored, shrinks, turns red and drop. The insect can likewise be spread out through fallen leaves.

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

Stink Bug: Sting bug is a severe pest which attacks the plant during blossom period so the crop yield entirely drops. This bug is seen around the tropical region.

The harmful enzyme in the plant shrinks the entire plant.

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

Tip borer caterpillar: The insects typically occurs attacks the plant in flowering season and this insect is seen extensively in tropical areas. The female bug laid the eggs on the tender part of the plant and the young larvae feed the young fruits and plant tips.

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