Abstract: In one aspect, the present invention provides methods for suppressing cracking, stem browning, and water loss in fruit or vegetables, such as cherries. The methods comprise applying to fruit or vegetables an amount of a wax emulsion effective to suppress cherry cracking, stem browning, and water loss. The wax emulsion used in the methods of the invention typically comprises a matrix of complex hydrocarbons, one or more emulsifying agents, and water. In some embodiments, the wax emulsion comprises from about 0.125% to about 25% (weight/weight) of carnauba wax, from about 0.1% to about 16% (weight/weight) of oleic acid, and from about 0.03% to about 6% (weight/weight) of morpholine, and from about 53% to about 99.7% (weight/weight) of water. In some embodiments, the wax emulsions further comprise one or more osmoregulators.

Abstract: Sunburn and insect damage to fruit and vegetable crops is significantly reduced by treatment of both fruit and foliage with a preventative amount of a wax emulsion comprising a matrix of complex hydrocarbons, an emulsifying agent and water. In the practice of this invention the sunburn and insect protective composition is further diluted in an aqueous solution that is sprayable by commercial applicators.
