Pests Of Jatropha

Jatropha Curcas is gaining value commercially as the demand of nonrenewable fuel sources increases tremendously and also Jatropha is an environment-friendly energy plantation. Plantation of this plant is thought about to be an outstanding fuel replacement and it is also very affordable compared to other fuels. Recently, Jatropha is facing some trouble with bugs and illness. The pests are classified into two varieties: Pest that impact young plants and Pest that affect developed plants.

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

Agrotis ipsilon: It is typically understood as Cut worm. This bug impacts 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 shrunk the plant entirely.

Control: This bug can be controlled by picking the larva discovered around the plants or by blending the bran, sawdust with insecticides.

Scarabaeid Beetle: This insect destroys the root of the young plant. Initially, the larva takes in the present in the soil and then comes to the root. The larva attack might kill the entire plant.

Control: The plant with great resistance power can conquer the pest. For heavy attack, insecticides with components carbosulfan and carbofuran can be utilized to eliminate the insect.

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

Control: Insecticides are utilized to control the insects.

Grasshopper: This is common insect found in a number of plants. Valanga nigricornis and Locusta migratoria widely attacks the plant. The insect often attacks 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 pest typically drop. The presence can be recognized by the larva penetration hole at the stem.

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

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

Leaf Caterpillar: This pest can eat all the leaves of the plant in other words period. The quality and yield of the seeds get lowered due to the heavy attack.

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

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

Control: Manually, the bug can be eliminated only 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 pointer. Later, the entire leaf dry and die.

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

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

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

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

Chrysocoris javanus, Tip borer caterpillar.

Stink Bug: Sting bug is a severe pest which assaults the plant during blossom period so the crop yield completely falls down. This bug is seen around the tropical region.

The toxic enzyme in the plant shrinks the entire plant.

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

Tip borer caterpillar: The bugs commonly occurs attacks the plant in blooming season and this pest 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 ideas.

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