Swinglea glutinosa LEAVES DERIVED MATERIAL, ALONE OR IN COMBINATION WITH COPPER SULFATE, FOR CONTROL OF SOUR ROT GRAPES AND BUNCH ROT GRAPES

Abstract

The invention of the present application provides a natural material derived from Swinglea glutinosa leaves that alone or in combination with copper sulfate is as good or better than pesticide combinations for controlling Botrytis cinerea bunch rot of grapes, and sour rot of grapes caused by Alternaria sp., Cladosporium sp., Aspergillus sp., Mucor sp., Rhizopus sp., and Penicilium sp. The material derived from Swinglea glutinosa leaves, by itself, has better results than any of the pesticide combinations for controlling both, sour rot and bunch rot. A preparation of the material derived from Swinglea glutinosa leaves in combination with copper sulfate is better than pesticide combinations for sour rot of grapes, and a very good alternative, instead of pesticide combinations, for Botrytis cinerea bunch rot of grapes.

Description

[0001]This application is a continuation in part of U.S. patent application Ser. No. 12 / 466,801, which has one inventor in common. U.S. patent application Ser. No. 12 / 466,801 is incorporated herein in its entirety by reference.BACKGROUND OF THE INVENTION[0002]1. Area of the Invention[0003]The present invention is related to how to treat Botrytis cinerea bunch rot grapes and sour rot grapes with an extract material derived from Swinglea glutinosa leaves and a preparation made of the material derived from Swinglea glutinosa leaves and copper sulfate. The extract is described by preceding pending unpublished U.S. patent application Ser. No. 12 / 466,801.[0004]2. Description of Prior Art[0005]Botrytis cinerea affects grape cultivation causing bunch rot to grapes resulting in great losses for wineries. Another winery loss known malady to grape cultivation is commonly called sour rot which is caused by a complex of microorganisms that include Alternaria sp., Cladosporium sp., Aspergillus sp...

Benefits of technology

[0008]The invention of the present application provides a natural material derived from Swinglea glutinosa leaves that alone or in combination with copper sulfate is as good or better than pesticide combinations for controlling Botrytis cinerea bunch rot of grapes, and sour rot of grapes caused by Alternaria sp., Cladosporium sp., Aspergillus sp., Mucor sp., Rhizopus sp., and Penicilium sp. The material derived from Swinglea glutinosa leaves, by itself, has better results than any of the pesticide combinations for controlling both, sour rot and bunch rot. A preparation of the material derived from Swinglea glutinosa leaves in combination with copper sulfate is better than pesticide combinations for sour rot, and a very good alternative, instead of pesticide combinations, for Botrytis cinerea bunch rot.

Problems solved by technology

Botrytis cinerea affects grape cultivation causing bunch rot to grapes resulting in great losses for wineries.

Both, Botrytis cinerea bunch rot and sour rot are hard to control and usually require rotation or mixes of multiple pesticides, e.g., a mix of fenhexamid and sulfur, or a mix of cyprodinil, fludioxonil, and sulfur, or a mix of copper oxichloride, copper sulfate, copper, and sulfur.

Unfortunately, there is no description in the prior art of a natural derived compound that alone or in a mix can diminish the use of the mentioned pesticides for control of Botrytis cinerea bunch rot and sour rot.
