Disease assessments were made in two citrus groves on Luzon and Mindinao Islands of the Philippines. Both groves were composed of Szinkom mandarin interplanted with Calamansi and occasional pummelo trees. The Luzon grove (VP) consistedof an older, heavily diseased block of trees and three younger blocks immediately adjacent to the east and northeast. All blocks were established with nursery stock, some of which was infected with greening. The Mindinao grove (BJ), consisting of 920 trees, was established from nursery stock a portion of which was probrably infected. Based on analysis of isopath maps of each block in the VP grove, aggregation of diseased trees existed in the three newer blocks but was not often associated with rows. Aggregates of diseased trees appeared to be coalescing over time and small individual clusters were generally indeterminate in shape. The oldest block of trees was > 90% diseased and no longer showed aggregation due to the nearly uniform distribution of trees with severe greening symptoms. Isophat maps of the BJ grove both groves. Morisita's-index-of-dispersion was interpreted to indicate that aggregates of 2 x 2, 3 x 3,4 x 4, and 6 x 6 trees existed and that aggregates of diseased trees larger than 6 x 6 also existed during the last disease assessments. This diffuse aggregation may have been the result of the random distribution of diseased planting materials followed by subsequent confluent and nondirectional spread of greening by psyllid vectors. |
