Pests Of Jatropha

Jatropha Curcas is gaining significance commercially as the need of nonrenewable fuel sources increases enormously and likewise Jatropha is an environment-friendly energy plantation. Plantation of this plant is thought about to be an excellent fuel replacement and it is also really affordable compared to other fuels. Recently, Jatropha is dealing with some problem with insects and illness. The bugs are classified into 2 ranges: Pest that impact young plants and Pest that impact grown plants.

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

Agrotis ipsilon: It is typically understood as . This pest 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 entirely.

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

Scarabaeid Beetle: This insect ruins the root of the young plant. Initially, the larva consumes the natural matters present in the soil and after that concerns the root. The larva attack might kill the entire plant.

Control: The plant with good resistance power can overcome the insect. For heavy attack, insecticides with components 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 might entirely kill the plants.

Control: Insecticides are used to control the pests.

Grasshopper: This prevails bug found in a number of plants. Valanga nigricornis and Locusta migratoria commonly attacks the plant. The bug frequently attacks 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 assaulted by this pest typically drop. The presence can be recognized by the larva penetration hole at the stem.

Control: The Insecticide generally used to manage this insect is carbofuran.

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

Leaf Caterpillar: This insect can consume all the leaves of the plant in brief period. The quality and yield of the seeds get minimized due to the heavy attack.

Control: This can be controlled by picking the old larvae around the surface and tossing away the attacked leaves.

Needle Caterpillar: This caterpillar is covered with spines and produces a burning experience when allowed to exposure to skin as it produces certain chemical substance. Initially the insect crowded in the leaf and then spread all over the plant when it gets older.

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

Leaf Hopper: This pest is discovered mainly in tropical and subtropical areas. The insect targets the leaf and draws all the nutrients of the leaf and gets curls at the idea. Later, the entire leaf dry and die.

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

Mite: Mite also attacks the leaf and makes the whole plant weak. The bug existence can be recognized when the leaf ended up being yellow-colored, shrinks, reddens and drop. The bug can also be spread out through fallen leaves.

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

Some dreadful bug which assaults flower and fruit are, Stink bug (Nezara viridula)

Chrysocoris javanus, Tip borer caterpillar.

Stink Bug: Sting bug is a serious pest which assaults the plant throughout bloom period so the crop yield totally drops. This bug is seen around the tropical region.

The toxic enzyme in the plant shrinks the entire plant.

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

Tip borer caterpillar: The pests commonly occurs attacks the plant in flowering season and this insect is seen extensively 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 tips.

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