Cottony cochineal. Small parasites covered in a white, cottony fluff that attack the leaf covers and the tender stems of plants in a plague.
It is a very damaging pest for all plants, sucking the sap to weaken them; Her favorite food is the young and tender tissues, that is, the new shoots. The adult cottony mealybugs and their larvae suck the sap from the host plants, which reduces plant growth.
How to eliminate mealy bugs
Home Treatment against Cottony Cochineal.
The most effective home treatment to eliminate cotton wool is alcohol. You must completely moisten an alcohol cloth and clean the whole plant of mealybugs make sure the cloth is soaked. In the most difficult areas to access, help yourself with a swab, moistened with alcohol. You can make a mixture of alcohol and soap which you apply with a brush or fine brush to the applied plant.
If the affected plant is very large you can use a sprayer and apply a mixture of diluted liquid soap with water and alcohol. Then you must pass a cloth to clean and remove the pillbugs from the affected areas.
In plants, trees and shrubs of strong stem can be attacked to the cottony scale insects with water to pressure of a hose
Ecological Treatment against Cottony Cochineal.
Plants like: fern, tobacco, oregano are usually plants that we use to exterminate the cottony cochineal. If we fumigate with these plants using their diluted infusion in water we will eliminate the pest, since they are a very effective biological poison.
We can use organic products such as potassium soap or neem oil, we make a mixture with these products and apply in small plants with some brush and larger plants we can use a sprayer. Ditomea soil can be applied on the affected leaves or stems since it does not affect the plant but it does affect the cochineals. You can apply paraffin or vegetable oil also sodium silicate in the months of May to June, such as mineral oil in August.
Chemical Control against Cottony Cochineal
When we detect the plague you must do two sprays in fifteen days with Folithion or Baytroid (Bayer), Cuprosán (Sandoz). If the infestation persists insist on the applications, in small or medium plants to detect cochineals it is necessary to remove plants from the pot to verify if they are present, the general characteristic is that the plant does not grow, if so you must verify that the plant does not have scale insects in the roots. The pot should be immersed in 20 to 30 minute intervals in a water mixture with a solution of Diazinon or Folithion (Actellic 50E or Folithion 50 EL).
The chemical treatments to be more effective should be directed towards the larvae that are more sensitive to these products, in adults the use of insecticides is more complicated since their shell protects them, they can make two applications of the insecticides as long as there is more number of larvae for better treatment efficacy. Some copper-based fungicide must be applied to fight against the fungus of the negril copper oxychloride is more optimal to stop the growth of this.
