Recently, Jatropha is facing some problem with bugs and diseases. The bugs are into two varieties: Pest that affect young plants and Pest that affect developed plants.

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

Agrotis ipsilon: It is typically referred to as Cut worm. This bug impacts 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 completely.

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

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

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

Control: Insecticides are used to control the pests.

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

Control: The insecticides used 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 harms the jatropha curcas stem and it is widely 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 manage this pest 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 simply put period. The quality and yield of the seeds get minimized due to the heavy attack.

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

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

Leaf Hopper: This pest is discovered mostly in tropical and subtropical regions. The bug targets the leaf and sucks all the nutrients of the leaf and gets curls at the suggestion. 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 assaults the leaf and makes the entire plant weak. The pest presence can be determined when the leaf ended up being yellowish, diminishes, reddens and fall down. The pest can likewise be spread out through fallen leaves.

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

Stink Bug: Sting bug is a major insect which attacks the plant during bloom period so the crop yield entirely falls down. This bug is seen around the tropical area.

The hazardous enzyme in the plant diminishes the entire plant.

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

Tip borer caterpillar: The pests frequently occurs attacks the plant in blooming season and this pest is seen widely in tropical regions. The female insect 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 recommended to burn. The insecticides like monocrotophos and bensultap are sprayed at the flowering season.
