SUMMARY:

Brazil is the fifth largest world producer of coconut (Cocos nucifera L.), with a production in the 2018/2019 harvest of approximately 1.55 million tons and with the expectation of production reduction for the 2019/2020 harvest due to phytosanitary problems. Coconut productivity would be better if it weren't for the damage caused by the numerous diseases and pests. Among them the atrophy of the crown and the micro-mite Aceria guerreronis, found in many regions in the world producing coconut. Crown atrophy is already considered an important pathosystem attacking coconut trees in Brazil, with significant effects in reducing productivity, even killing the plant. The micro-mite A. guerreronis likewise has a significant impact on coconut cultivation, as it causes a drop in coconut tree productivity. A. guerreronis has been reported to have an impact on crops such as Açaí, Castanha-do-Pará, Palm oil, Macadamia, Pinhão, Pupunha. Thus, works aimed at the control and adequate management of these diseases become necessary, impacting on the reduction of control costs. In this work, studies were carried out in coconut monoculture areas, in two producing poles in the state of Pará, in order to study the spatial distribution of crown atrophy on coconut trees in the northeast region of the Brazilian Amazon, through geostatistics, and also to study the distribution of spray volume applied by means of application technology using electrostatic spraying, to evaluate the efficiency of coverage in combating the micro-mite A. guerreronis. It was verified through the geostatistics technique that the disease atrophy of the coconut palm crown, presented an aggregated spatial distribution. With the use of geostatistics, it was found that the spatial dependence of the atrophy of the crown varied from 14 to 135 meters.
