Plantation of this plant is considered to be an excellent fuel replacement and it is also very economical compared to other fuels. Recently, [Jatropha](https://www.zonebourse.com/cours/action/MISSION-NEWENERGY-LIMITED-8557641/) is facing some problem with pests and diseases. The pests are classified into two ranges: Pest that affect young plants and Pest that affect grown plants.<br>
 <br>Young plant insects: Cutworm, [Scarabeid](https://www.google.com/search?kgmid=/m/0cqd_rb) Beetle, Army worm, Grasshopper.<br>
 <br>Agrotis ipsilon: It is commonly understood as Cut worm. This insect affects the seedlings and young [Jatropha](https://www.zoominfo.com/c/mission-newenergy/346542889) plants. If the plant is affected by the cutworm, the stem gets [cut nearer](https://www.intelligentinvestor.com.au/shares/asx-mbt/mission-newenergy-limited/share-price) to the soil surface area and this will diminished the plant entirely.<br>
 <br>Control: This pest can be controlled by choosing the larva found around the plants or by blending the bran, sawdust with insecticides.<br>
 <br>Scarabaeid Beetle: This insect ruins the root of the young plant. Initially, the larva consumes the raw materials present in the soil and then pertains to the root. The larva attack may eliminate the whole plant.<br>
 <br>Control: The plant with great resistance power can [overcome](https://biodieselmagazine.com/articles/felda-global-buys-missions-kuantan-port-plant-for-11-5-million-9053) the bug. For heavy attack, insecticides with parts carbosulfan and carbofuran can be used to eliminate the pest.<br>
 <br>Army worm: Spodoptera litura existence can be identified by biting in the leaves. The serious infection might completely eliminate the plants.<br>
 <br>Control: Insecticides are used to control the insects.<br>
 <br>Grasshopper: This is typical bug found in numerous plants. Valanga nigricornis and Locusta migratoria widely attacks the plant. The bug typically assaults the young plant.<br>
 <br>Control: The insecticides utilized betacyfluthrin, cypermethrin, thiodicarb, MIPC, and fipronil.<br>
 <br>Pest observed in fully grown plants:<br>
 <br>Pest of Stem: Ostrinia furnacalis, Xyleborus spp.<br>
 <br>Ostrinia furnacalis and Xyleborus: This insect harms the [jatropha curcas](https://www.nasdaq.com/market-activity/ipos/overview?dealId=804419-65608) stem and it is extensively seen in Indonesia. The stem attacked by this insect usually drop. The presence can be determined by the larva penetration hole at the stem.<br>
 <br>Control: The Insecticide usually utilized to manage this insect is carbofuran.<br>
 <br>Pest of leaf: The common bugs observed are leaf caterpillar, Neetle caterpillar, Leaf hopper, Mite, Ear corn caterpillar.<br>
 <br>Leaf Caterpillar: This pest can consume all the leaves of the plant simply put duration. The quality and yield of the seeds get reduced due to the heavy attack.<br>
 <br>Control: This can be controlled by selecting the old larvae around the [surface](https://www.proactiveinvestors.com.au/ASX:MBT/Mission-NewEnergy-Ltd) and getting rid of the attacked leaves.<br>
 <br>Needle Caterpillar: This caterpillar is covered with spinal columns and produces a burning feeling when [enabled](https://www.zoominfo.com/c/mission-newenergy/346542889) to call with skin as it produces specific chemical [compound](https://www.sec.gov/Archives/edgar/data/1463471/000165495419013063/R31.htm). Initially the [pest crowded](https://biodieselmagazine.com/articles/felda-global-buys-missions-kuantan-port-plant-for-11-5-million-9053) in the leaf and after that spread all over the plant when it gets older.<br>
 <br>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](https://www.businessnews.com.au/Company/Mission-NewEnergy).<br>
 <br>Leaf Hopper: This insect is found mostly in [tropical](https://www.pinterest.com.au/missionnewenergy/) and subtropical areas. The [bug targets](https://www.abnnewswire.net/companies/en/31347/%E0%B8%9A%E0%B8%A3%E0%B8%B4%E0%B8%A9%E0%B8%B1%E0%B8%97-Mission-NewEnergy-%E0%B8%88%E0%B8%B3%E0%B8%81%E0%B8%B1%E0%B8%94.html/4) the leaf and sucks all the nutrients of the leaf and gets curls at the tip. Later, the entire [leaf dry](https://biodieselmagazine.com/articles/felda-global-buys-missions-kuantan-port-plant-for-11-5-million-9053) and pass away.<br>
 <br>Control: The heavy attack can be controlled by utilizing insecticides like imidachloprid, beta cyfluthrin or [carbosulfan](https://www.crunchbase.com/organization/mission-newenergy).<br>
 <br>Mite: Mite also [attacks](https://stocktwits.com/symbol/MNEL) the leaf and makes the entire plant weak. The insect presence can be [recognized](https://www.proactiveinvestors.co.uk/companies/news/159352/mission-newenergy-debt-free-focused-on-biofuel-joint-venture-60797.html) when the leaf become yellowish, shrinks, turns red and fall down. The pest can also be spread through fallen leaves.<br>

 <br>The hazardous enzyme in the plant shrinks the entire plant.<br>
 <br>Control: Insecticides recommended for this bug is chlorfluazuron, diflubenzuron, alfamethrin, and lamda cyhalothrin.<br>
