English Title: Efficacy of Anthranilate de Methyl, a repellent product on bird pressure in strict rainfed rice
English Abstract
In Côte d'Ivoire, bird damage is one of the main concerns of rice farmers, due to large losses of production induced. Human surveillance from milky stage to maturity, which is the most widely used means of bird control, is effective but has shown its limits. An alternative to human surveillance has been tested. Work on evaluation of Anthranilate de Methyl repellent was conducted in field, research station and laboratory. Trial conducted at CNRA research station in Man, consisted in evaluating 05 application modalities of the product under strict rainfed rice conditions. Variables analyzed are rate of emergence, percentage of panicles attacked by birds per m², percentage of empty grains per panicle due to birds, and yield in paddy. In laboratory, toxicity level of the repellent product was determined by OCDE process. Results show that Anthranilate de Methyl makes it possible to reduce damage caused by grain-eating birds, especially by applying it to milky stage of grains, in strict rainfed rice production. Paddy yield obtained in plot treated with repellent was significantly the same as that obtained in plot under human protection. Anthranilate de Methyl has reduced yield losses due to avian damage by 45-80%. However, for greater efficacy of repellent product, post-seeding treatment and 02 post-emergence applications are required. In addition, laboratory analyzes have shown that the repellent product is non-toxic. However, it may be found to be hazardous by inhalation and for the eyes. Therefore, application of Anthranilate de Methyl will require appropriate safeguards, namely: wearing protective clothing and masks Gas, finally ensure that there is no one in the vicinity within a radius of at least 50 m around the treated parcel.
