Jatropha Curcas is getting value commercially as the need of nonrenewable fuel sources increases significantly and likewise Jatropha is an environmentally friendly energy plantation. Plantation of this plant is thought about to be an exceptional fuel alternative and it is likewise very cost-effective compared to other fuels. Recently, Jatropha is facing some trouble with bugs and diseases. The insects are classified into two ranges: Pest that affect young plants and Pest that impact grown plants.

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

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

Control: This pest can be controlled by selecting the larva discovered around the plants or by blending the bran, sawdust with insecticides.

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

Army worm: Spodoptera litura existence can be recognized by biting in the leaves. The serious infection might completely eliminate the plants.

Control: Insecticides are used to manage the bugs.

Grasshopper: This is typical bug found in numerous plants. Valanga nigricornis and Locusta migratoria extensively attacks the plant. The bug 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 harms the Jatropha stem and it is extensively seen in Indonesia. The stem attacked by this bug generally drop. The existence can be determined by the larva penetration hole at the stem.

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

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

Leaf Caterpillar: This bug can eat all the leaves of the plant in short duration. 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 tossing away the assaulted leaves.

Needle Caterpillar: This caterpillar is covered with spinal columns and produces a burning sensation when allowed to exposure to skin as it produces specific chemical substance. Initially the insect crowded in the leaf and then spread out all over the plant when it ages.

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

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

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

Mite: Mite likewise attacks the leaf and makes the entire plant weak. The insect presence can be determined when the leaf ended up being yellow-colored, diminishes, turns red and fall down. The bug can likewise be spread through fallen leaves.

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

The toxic enzyme in the plant diminishes the entire plant.

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

Tip borer caterpillar: The bugs frequently takes place attacks the plant in flowering season and this insect is seen commonly in tropical regions. The female pest laid the eggs on the tender part of the plant and the young larvae feed the young fruits and plant tips.

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