Question: parasite on parsley


I wanted to ask a question about parsley.
I have this plant which has a strange little white parasite both on the base and on the stems and leaves. He really invaded the whole plant.
What natural remedies can I use?
Thanks


Parsley with parasite: Answer: parasite on parsley


Dear Federico,
small white insects could be white flies, although these insects usually grow in areas with poor air exchange, with hot and humid climate (in fact they are among the most feared insects by those who have a greenhouse); in this case, in addition to the tiny mosquini, which rise in a cloud when you move the leaves, you should notice small insects without wings, positioned on the underside of the leaves of your parsley. These are the juvenile stages of the insect, which are also the most harmful to your parsley. To eradicate these insects it is often necessary to practice more than one treatment, at regular intervals, because they often tend not to be affected, thanks to a waxy patina that is produced to protect the juvenile larvae and insects; to get around this substance, the insecticide is often mixed with white oil, the same that is used against cochineal: this mineral oil passes through the waxy patina and allows the insecticide to hit the insects directly. Since it is parsley, consider that before using it, even after the correct deficiency period, you will have to wash it thoroughly. So you can first try a broad spectrum insecticide, if you see that it doesn't defect the insect, then try mixing it with white oil; after all, when you see that the insects are dead, you can also think of cutting all the parsley, throwing it and waiting for it to be healthy. What product to use: there are many insecticides on the market, based on synthetic products, such as imidaclopryd or pyrethrins, or products that can be used in organic farming, such as natural pyrethrum, some pyrethrins or neem oil; all these products are good against whitefly, and all, even those used in organic farming, have a shortage period, during which they are active and parsley should not be eaten. After this period, the leaves can be used without problems. In organic farming, against white flies, an insect is used that parasitizes the juvenile forms, called encarsia; on the market there are some small paper panels, which contain white fly nymphs parasitized with encarsia; these small panels are placed near the plants hit by the parasite, and from there the incarsities move on the insects to be eradicated. Clear that this method is more expensive than a pyrethrum based insecticide canister, and therefore is motivated only in the case of large crops, whose parasites carry economic damage. When using a broad spectrum insecticide choose the evening hours, and avoid spraying it in areas where there are bees or other useful insects.
