The Ministry of Agriculture and Water has managed to control the plague of wormy walnut (Carpocapsa) in Moratalla, engineering applications and reducing them by using pheromone traps.
The CEO of agribusiness and agricultural training, Lidón Angel Garcia, said that the "Ministry for years encouraged the cultivation techniques and pest control minimal or no environmental impact, which is ahead of the demands that are now imposed by the European Union. "
In this regard, he noted that last September, the Ministry of Agriculture, Food and Environment approved a Royal Decree to achieve a sustainable use of plant protection products, which includes measures and obligations, among others, for the production sector, which should move towards integrated pest management and alternative techniques.
Such demands, Garcia Lidón, "not involve higher costs for farmers, but significant savings on products and application times, labor and machinery, as revealed in this experience of control wormy walnut Moratalla, which can be extended to the apple and pear. "
The responsible regional stated that "the slightest application of pesticides and proper choice means reducing environmental problems and reduce the likelihood of resistance appear and less useful to wildlife disease who keeps other pests such as mites."
The District Agricultural Office (OCA) Northwest, performing a test of 14 varieties of walnut and pruning techniques, which aims to determine the vegetative and productive characteristics of each sector to transfer the most suitable and profitable.
At the same time takes place, in order to avoid its wormy, weekly count butterfly catch, responsible for originating the pest.
According to Pedro José Guirao, said OCA director, larvae of the pest, from the clutches of those butterflies, galleries are looking for seeds in the holes and, more abundant at the contact between fruit, dark debris accumulate wet sawdust .
This causes major damage as the fall and fruit rotting.
Both treatments performed the last months of May and June, when pheromone traps indicated maximum flight, have served to completely control the said pest, to the point of not detecting a walnut or wormy.
This contrasts, as Pedro Guirao, with six or seven treatments that must be performed in intensive cultivation of walnut or apple to keep them protected during the sensitive period, from May to September, by farmers who know the development of flight and optimum treatment time.
In this regard, he noted that while adults catch exceeds a critical level, set at 0.8 catches per trap per day for cultivation and the area, no applications are made against this pest.
When this threshold is exceeded, it indicates that an update is taking risk and, depending on the temperature, wormy begin in six or eight days, so that, only then it is advisable to treat with a product or ovicidal larvicide.
