Abstract: The invention consists of a mixture of organic chemicals avoiding the use of insecticides, and a method for pest control based on the mixture consisting in bringing about the premature eclosion of the hibernating larva and its possible death through inanition; experimentation has demonstrated it to be effective in bringing about the premature eclosion of the pecan nut casebearer or Acrobasis nuxvorella (Lepidoptera: Pyralidae) on pecan trees (Carya illinoiensis). The objective is to provide an ecological method for controlling pests such as the pecan nut casebearer, in this manner reducing or avoiding the use of inorganic chemical insecticides which have a significant impact on the environment.

Abstract: The present invention claims a method making it possible to control the color of table grapes, color being a quality factor for the marketing thereof. The traditional color promotion pathways make use of products such as Ethrel and methyl jasmonate (MeJA), which liberate or induce ethylene to improve color, these being applied during veraison to augment the color of the berries determined by the quantity and composition of skin anthocyanins. One alternative to the use of these compounds are the oligogalacturonides (OGAs) having a degree of polymerisation in the range from DP 7-20 which have the capacity to induce anthocyanins by an alternative pathway. The synthesis and precise application of OGAs form a method permitting appropriate control of the coloration of this type of fruit, together with the quantification of total anthocyanins.
