In the presence of particularly delicate plants, it is advisable to test the product first and if it is necessary to move this operation in the evening, to avoid leaf burns.
Eliminate aphids and cochineal with theMarseille soap
Preparation: in liquid form, dilute 20-30 cc of Marseille soap in a liter of water. In the case of Marseille soap in solid form, add 80 grams of Marseille soap in flakes (cut it!) And let it dissolve in a liter of water. If the weather is cool, you will have to wait as much as 20 days for the soap to dissolve completely.
Use: it is particularly suitable against cochineal, as its insecticidal action consists in obstructing the respiratory organs of these parasites. But it can also prove effective against other parasites. Also in this case it is better to hit the insects directly, administering the remedy in the evening hours.

L'mineral oilis used asinsecticide broad spectrum. It is obtained from the fractional distillation of crude oil and can be compared toparaffins(synthetic waxes), in fact similarly belong to the aliphatic hydrocarbon compounds with high molecular weight.
This type of oil must be used according to the methods indicated on the label, usually it is a solution to be sprayed on the whole plant: when sprayed on infected plants, this product will create a sort of film that covering the mealybugs it will cause death by suffocation.
Where to find themineral white oil? In shops specializing in the sale of plant protection products or by taking advantage of online purchases. There are a large number of products on Amazon. For completeness I point out the page:White mineral oil on Amazon.
Mineral oil is an oil that manages to eliminate scale insects causing them to suffocate. Other insecticides are ineffective because the scale insects produce a protective substance that does not allow the penetration of classic contact insecticides. It can be used pure for the treatment of an infestation of mealybug or aphids in progress while it can be used diluted (dilution 1:50) with water in case of preventive treatment.
