Pests Of Jatropha

Jatropha Curcas is gaining importance commercially as the demand of nonrenewable fuel sources increases enormously and also Jatropha is an plantation. Plantation of this plant is considered to be an exceptional fuel alternative and it is also extremely affordable compared to other fuels. Recently, Jatropha is facing some trouble with insects and diseases. The bugs are classified into two varieties: Pest that impact young plants and Pest that affect developed plants.

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

Agrotis ipsilon: It is typically called Cut worm. 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 choosing the larva found around the plants or by mixing the bran, sawdust with insecticides.

Scarabaeid Beetle: This pest ruins the root of the young plant. Initially, the larva takes in the organic matters present in the soil and then concerns the root. The larva attack may eliminate the entire plant.

Control: The plant with good resistance power can overcome the bug. For heavy attack, insecticides with elements carbosulfan and carbofuran can be utilized to kill the bug.

Army worm: Spodoptera litura existence can be determined by biting in the leaves. The extreme infection might totally eliminate the plants.

Control: Insecticides are utilized to control the insects.

Grasshopper: This is common insect discovered in a number of plants. Valanga nigricornis and Locusta migratoria widely assaults 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 stem and it is extensively seen in Indonesia. The stem assaulted by this insect normally drop. The presence can be determined by the larva penetration hole at the stem.

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

Pest of leaf: The typical 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 in brief period. The quality and yield of the seeds get minimized due to the heavy attack.

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

Needle Caterpillar: This caterpillar is covered with spinal columns and produces a burning sensation when permitted to call with skin as it produces specific chemical substance. Initially the insect crowded in the leaf and after that spread out all over the plant when it ages.

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

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

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

Mite: Mite likewise attacks the leaf and makes the whole plant weak. The pest existence can be recognized when the leaf ended up being yellowish, diminishes, turns red and fall down. The insect can also be spread through fallen leaves.

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

Some awful pest which attacks flower and fruit are, Stink bug (Nezara viridula)

Chrysocoris javanus, Tip borer caterpillar.

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

The toxic enzyme in the plant shrinks the entire plant.

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

Tip borer caterpillar: The pests typically occurs attacks the plant in blooming season and this pest is seen widely in tropical regions. 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.
