Pests Of Jatropha

Jatropha Curcas is acquiring value commercially as the demand of fossil fuels increases enormously and also Jatropha is an environment-friendly energy plantation. Plantation of this plant is thought about to be an exceptional fuel alternative and it is also really cost-effective compared to other fuels. Recently, Jatropha is dealing with some problem with bugs and diseases. The insects are categorized into two ranges: Pest that affect young plants and Pest that affect matured plants.

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

Agrotis ipsilon: It is commonly called Cut worm. This pest affects the seedlings and young Jatropha plants. If the plant is impacted by the cutworm, the stem gets cut nearer to the soil surface and this will diminished the plant entirely.

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 pest damages the root of the young plant. Initially, the larva consumes the natural matters present in the soil and then comes to the root. The larva attack may eliminate the whole plant.

Control: The plant with great can get rid of the bug. For heavy attack, insecticides with parts carbosulfan and carbofuran can be used to eliminate the insect.

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

Control: Insecticides are used to manage the pests.

Grasshopper: This prevails pest discovered in several plants. Valanga nigricornis and Locusta migratoria commonly attacks the plant. The pest often 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 stem and it is widely seen in Indonesia. The stem assaulted by this pest normally drop. The existence can be determined by the larva penetration hole at the stem.

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

Pest of leaf: The typical 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 in other words duration. 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 discarding the attacked leaves.

Needle Caterpillar: This caterpillar is covered with spinal columns and produces a burning sensation when enabled to contact with skin as it produces specific chemical compound. Initially the bug crowded in the leaf and after that spread all over the plant when it ages.

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

Leaf Hopper: This insect is discovered mostly in tropical and subtropical regions. The bug targets the leaf and draws all the nutrients of the leaf and gets curls at the idea. Later, the whole leaf dry and die.

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

Mite: Mite also assaults the leaf and makes the entire plant weak. The insect existence can be determined when the leaf become yellow-colored, shrinks, turns red and fall down. The pest can also be spread out through fallen leaves.

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

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

Chrysocoris javanus, Tip borer caterpillar.

Stink Bug: Sting bug is a severe insect which assaults the plant during bloom duration so the crop yield entirely drops. This insect is seen around the tropical region.

The toxic enzyme in the plant diminishes the whole plant.

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

Tip borer caterpillar: The bugs commonly takes place attacks the plant in flowering season and this bug is seen widely 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 assaulted seeds are advised to burn. The insecticides like monocrotophos and bensultap are sprayed at the blooming season.
