What about yellow spot

Hi Satish ! Your leaf is attacked by Leaf Miner Flies. The yellow halo spots may be die to Sooty Mold For details please click the link above to plantix library. Thanks for visiting plantix community

Thanks Dhiraj Mehta for your support

Your always welcome Dr. V Pandey sir.

My pleasure Dhiraj Mehta ji

Which is the chemical better to control this one Satish Dr. V Pandey Dhiraj Mehta

Hi Rakshith ! Leafminers feed on the nutrients in leaves, mining out the plant tissue and creating white trails on the foliage. On vegetable crops, the most common leafminers belong to the genus Liriomyza. Affected leaves often drop prematurely and severe infestation can cause plants to lose all foliage. Several control methods can help you prevent and manage leafminers in your vegetable garden. Proper control of leafminers on vegetables starts with proper identification. Adult leafminers typically look like small black and yellow flies, although some insects look more silvery-gray in color. The larvae look like very small, yellowish-colored maggots feeding on the undersides of the leaves. Check underneath the leaves for masses of tiny cream-colored, oval eggs and crush any eggs that you find. Once hatched, the larvae leave a winding, white trail behind as they feed, so keep an eye out for that symptom. Cultural Control You can help prevent the spread of leafmining insects by checking your transplants before planting them in your vegetable garden. Destroy any infested plants immediately. Look for vegetable varieties that are less susceptible to leafminer infestation, such as tomato cultivars with curled leaves. Don't plant any vegetables in areas where you've had previous leafminer infestations. Always remove any remaining old plants at the end of the growing season. Biological Control Leafminers on vegetable crops are frequently kept under control by their natural enemies, particularly parasitic wasps such as the Diglyphus begini and Chrysocharis parksi. These wasps feed on the leafminer larvae and can significantly reduce leafminer populations. In the absence of any type of broad-spectrum insecticide on your plants, the wasps should provide you with natural biological control. Chemical Control It's better not to use any type of chemical controls to manage leafminer infestations. Not only will the chemicals kill off the leafminer's natural predators, but the insects have developed a resistance to insecticides containing carbamates, pyrethroids and organophosphates. Using any of those chemicals will likely make your leafminer populations increase in size. If you feel that you must use chemical controls, then Avermectin, a microbially derived insecticide, seems to kill the leafminers but not their predators. The University of California recommends spraying Spinosad to control leafminers on organically certified crops. For sooty mold you can use copperoxychloride 0.25% solution in water. Thanks and all the best
