Jatropha Curcas is getting significance commercially as the need of nonrenewable fuel sources increases significantly and likewise Jatropha is an environmentally friendly energy plantation. Plantation of this plant is considered to be an outstanding fuel substitute and it is likewise very affordable compared to other fuels. Recently, Jatropha is facing some trouble with pests and diseases. The pests are categorized into 2 ranges: Pest that affect young plants and Pest that affect developed plants.

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

Agrotis ipsilon: It is frequently referred to as Cut worm. This bug 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 bug can be managed by picking the larva discovered around the plants or by blending the bran, sawdust with insecticides.

Scarabaeid Beetle: This bug ruins the root of the young plant. Initially, the larva takes in the organic matters present in the soil and then comes to the root. The larva attack may kill the entire plant.

Control: The plant with great resistance power can get rid of the pest. For heavy attack, insecticides with elements carbosulfan and carbofuran can be utilized to kill the insect.

Army worm: Spodoptera litura presence can be determined by biting in the leaves. The severe infection could completely kill the plants.

Control: Insecticides are to manage the bugs.

Grasshopper: This is common bug found in several plants. Valanga nigricornis and Locusta migratoria commonly assaults 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 insect harms the Jatropha stem and it is extensively seen in Indonesia. The stem attacked by this insect typically drop. The existence can be identified by the larva penetration hole at the stem.

Control: The Insecticide usually utilized to control this bug is carbofuran.

Pest of leaf: The common 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 simply put duration. The quality and yield of the seeds get decreased due to the heavy attack.

Control: This can be managed by choosing the old larvae around the surface area and getting rid of 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 certain chemical substance. Initially the pest crowded in the leaf and then spread 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 bug is found mostly in tropical and subtropical regions. The pest targets the leaf and draws all the nutrients of the leaf and gets curls at the tip. 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 assaults the leaf and makes the entire plant weak. The insect presence can be recognized when the leaf ended up being yellow-colored, diminishes, turns red and drop. The pest can also be spread through fallen leaves.

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

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

The hazardous enzyme in the plant shrinks the entire plant.

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

Tip borer caterpillar: The bugs commonly takes place attacks the plant in blooming season and this bug is seen extensively in tropical areas. The female insect laid the eggs on the tender part of the plant and the young larvae feed the young fruits and plant pointers.

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