WILT-PRUF acts as a protective coating, holding in moisture on plant foliage and stems, substantially reducing water loss during periods of plant stress. WILT-PRUF spray dries to form a clear, colorless, flexible, gloss film without interfering with plant growth or materially affecting respiration, osmosis, or photosynthesis.
When we say spray at a dilution rate of 1:10 or 1:5 we mean to use one part of concentrate to five or ten parts water. A "part" may be a pint, a quart, a gallon, or any measured quantity.
For winter kill protection, spray in late fall at a dilution rate of 1:5 when temperature is above freezing so that spray will not freeze on foliage. When spraying on arborvitae, cypress, juniper, and cedar; be aware that if these species have not sufficiently hardened off for the winter whereby moisture retreats to the root system, moisture in plant cells could freeze and burst if early severe freezing weather should occur.
For drought, windburn, transplanting, and bulb storage protection - dip or spray to run-off at a dilution rate of 1:10.
For Christmas trees, wreaths, and greens spray as above. In all cases, WILT-PRUF must dry outdoors in daylight. WILT-PRUF will turn Blue Spruce green temporarily. Always follow instruction on label carefully.
