Jatropha Curcas is gaining importance commercially as the need of fossil fuels 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 really cost-effective compared to other fuels. Recently, Jatropha is dealing with some problem with insects and diseases. The pests are classified into two ranges: Pest that impact young plants and Pest that impact matured plants.
Young plant bugs: Cutworm, Scarabeid Beetle, Army worm, Grasshopper.
Agrotis ipsilon: It is typically referred to as Cut worm. This bug affects 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 shrunk the plant entirely.
Control: This bug can be managed by choosing the larva discovered around the plants or by mixing the bran, sawdust with insecticides.
Scarabaeid Beetle: This 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 might eliminate the entire plant.
Control: The plant with excellent resistance power can overcome the pest. For heavy attack, insecticides with components carbosulfan and carbofuran can be utilized to eliminate the pest.
Army worm: Spodoptera litura existence can be determined by biting in the leaves. The serious infection could completely eliminate the plants.
Control: Insecticides are used to control the insects.
Grasshopper: This prevails bug found in numerous plants. Valanga nigricornis and Locusta migratoria commonly attacks the plant. The insect typically assaults the young plant.
Control: The insecticides used betacyfluthrin, cypermethrin, thiodicarb, MIPC, and fipronil.
Pest observed in mature plants:
Pest of Stem: Ostrinia furnacalis, Xyleborus spp.
Ostrinia furnacalis and Xyleborus: This pest damages the jatropha curcas stem and it is commonly seen in Indonesia. The stem attacked by this bug generally fall down. The presence can be recognized by the larva penetration hole at the stem.
Control: The Insecticide typically used to control this pest is carbofuran.
Pest of leaf: The typical bugs observed are leaf caterpillar, Neetle caterpillar, Leaf hopper, Mite, Ear corn caterpillar.
Leaf Caterpillar: This bug can eat all the leaves of the plant in brief period. The quality and yield of the seeds get decreased due to the heavy attack.
Control: This can be controlled by selecting the old larvae around the surface area and tossing away the assaulted leaves.
Needle Caterpillar: This caterpillar is covered with spines and produces a burning experience when permitted to call with skin as it produces specific chemical compound. Initially the pest crowded in the leaf and then spread all over the plant when it grows older.
Control: Manually, the bug can be killed just by soaking it in water or kerosene. The heavy attack can be controlled by spraying organophosphate insecticides.
Leaf Hopper: This pest is found mostly in tropical and subtropical regions. The insect targets the leaf and sucks 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 managed by utilizing insecticides like imidachloprid, beta cyfluthrin or carbosulfan.
Mite: Mite also assaults the leaf and makes the entire plant weak. The insect existence can be recognized when the leaf ended up being yellowish, shrinks, turns red and fall down. The pest can likewise be spread through fallen leaves.
Control: Some preventive procedures can be done like appropriate sanitation and burning the fallen leaves. Heavy attack can be dealt with by spraying insecticides.
Some awful bug which attacks flower and fruit are, Stink bug (Nezara viridula)
Chrysocoris javanus, Tip borer caterpillar.
Stink Bug: Sting bug is a major pest which assaults the plant throughout bloom duration so the crop yield completely falls down. This pest is seen around the tropical area.
The toxic enzyme in the plant diminishes the whole plant.
Control: Insecticides recommended 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 insect is seen widely in tropical regions. 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 attacked seeds are recommended to burn. The insecticides like monocrotophos and bensultap are sprayed at the flowering season.
