Plantation of this plant is thought about to be an exceptional fuel replacement and it is also extremely affordable compared to other fuels. Recently, jatropha curcas is facing some problem with pests and diseases. The pests are classified into two ranges: Pest that impact young plants and Pest that affect developed plants.


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


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


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

Control: The plant with great resistance power can conquer the bug. For heavy attack, insecticides with components carbosulfan and carbofuran can be utilized to kill the pest.


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


Control: Insecticides are used to manage the insects.


Grasshopper: This is typical bug found in a number of plants. Valanga nigricornis and Locusta migratoria commonly attacks the plant. The pest typically 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 insect damages the Jatropha stem and it is extensively seen in Indonesia. The stem attacked by this pest usually drop. The presence can be recognized by the larva penetration hole at the stem.


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


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


Leaf Caterpillar: This pest can consume all the leaves of the plant simply put duration. The quality and yield of the seeds get reduced due to the heavy attack.


Control: This can be managed by choosing the old larvae around the surface area and getting rid of the attacked leaves.


Needle Caterpillar: This caterpillar is covered with spines and produces a burning sensation when allowed to exposure to skin as it produces certain chemical compound. Initially the insect crowded in the leaf and after that spread all over the plant when it ages.


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


Leaf Hopper: This insect is found primarily in tropical and subtropical areas. The bug targets the leaf and sucks all the nutrients of the leaf and gets curls at the tip. Later, the whole leaf dry and die.


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

Tip borer caterpillar: The pests frequently occurs attacks the plant in blooming season and this pest is seen commonly 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 ideas.


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