Commercial applications of “Shemer” for the control of pre- and post-harvest diseases
“Shemer” is a biofungicide based on the yeastMetschnikowiafructicola. Its mode of action is believed to be mainly through competition.The commercial product is stable under ambient storage, and can be applied by spray or drench application in the field or in packing houses. “Shemer” treatments in commercial packing houses significantly reduced the development ofPenicillium digitatumon oranges, and ofRhizopus stoloniferandFusariumsp. on sweet potatoes. Similarly, significant reduction was achieved in the development ofR. stoloniferon peaches,Botrytis cinereaon pepper andSclerotinia sclerotiumon carrots in pilot-scale tests. Application of “Shemer” in the field also proved useful in protecting fruits after harvest, where post-harvest treatments are not practiced. Weekly “Shemer” application on strawberry reduced rot development in the field and also the incidence of grey mould (B. cinerea) and Rhizopus fruit rot (R. stolonifer) during storage. In table grapes, application of “Shemer” 24 h beforeharvest,significantly reduced the number of decayed berries caused byB. cinerea,R. stoloniferorAspergillusafter storage. In most of the trials, the level of decay control was comparable to that of the most common chemical fungicides currently used by the industry. These results demonstrate the suitability of “Shemer” to a wide range of crop-pathogen, agricultural practices and climatic conditions.
