- Abstract
The present study contributes to the knowledge of the spatial distribution of anthracnose (Colletotrichum gloeosporioides) in avocado orchards in the State of Mexico. The study was carried out in the municipalities of Coatepec Harinas, Tenancingo, Donato Guerra and Temascaltepec. Geostatistical methods were used to determine the spatial distribution of anthracnose. Samples were conducted biweekly during the months of July to December 2018. By randomly selecting 200 trees per municipality, they were geographically geo-referenced using a Trimble eTrex model navigator. The spatial distribution of anthracnose in avocado cultivation showed differences in each of the municipalities evaluated, adjusting to different geostatistical models (Gaussian, spherical and exponential), which were validated by the cross-validation method. The spatial distribution of anthracnose was obtained with maps drawn up through ordinary krigeado. These maps revealed that the municipality of Tenancingo had the highest anthracnose density, compared to the municipalities of Coatepec Harinas, Temascaltepec and Donato Guerra. The spatial distribution of anthracnose in the four municipalities presented aggregation and localized sources of infection. This study concludes that geostatistical methods are an alternative to improve disease management programs such as anthracnose and help to adequately conduct control.
