Protecta Concentrated Arboricultural Whitewash UAB 1.5L Tub

Protecta Concentrated Tree Whitewash is a limewash-based coating, an age-old technique for protecting trees from various diseases and parasites. It is one of those winter treatments, known as 'foundation' treatments, somewhat neglected in recent years, yet their effectiveness is proven, as is their harmlessness to the environment. Applied preventatively, this treatment will save the gardener a number of problems and will help reduce the use of fungicides and insecticides during the growing season. Once diluted, apply this liquid preparation to the trunks or the base of the main scaffold branches, with a brush or sprayer, in one or two coats. 1.5 litres makes up to 6L of whitewash.

Applied to dry bark in the heart of winter, tree whitewash provides continuous and uniform protection for trunks and the base of main scaffold branches. It is composed of lime (calcium hydroxide) mixed with clay to thicken it and improve its adherence, and water. Once applied, it provides a physico-chemical protection with recognised antiseptic properties.

Tree whitewash, due to its alkalinity (very high pH), is unfavourable for the germination and development of pathogenic fungi such as fruit tree canker (Neonectria galligena), scabs, brown rot and peach leaf curl, whose spores hide in bark fissures in winter. Its presence also limits the development of mosses and lichens; it suffocates and destroys the larvae of certain pests, which also find refuge in the bark. Furthermore, the limewash reduces the phenomenon of exudation when planting standard trees. Due to its white colour, which reflects light and limits temperature variations, the limewash protects young bark and graft points from sunscald as well as from late frosts. Arboricultural whitewash is recommended for protecting pip and stone fruit trees, ornamental trees (limes, horse chestnuts, during top-grafting operations, etc...) 

The duration of protection, for a single application, depends on the quantity applied and precipitation: it is estimated between 8 and 12 weeks for an aerosol application, and 4 to 6 months depending on the thickness applied. A second application the following day significantly increases the persistence duration of the whitewash on the trunk and the base of the main scaffold branches.
