A survey was conducted to research on planting system and pesticide spray methods including volume, sprayer types, nozzles used in apple orchards. The deployed 395 farmers 17 cities towns 7 regions which are major producers of via interview. Major varieties were Fuji (79.2%) Hongro (50.9%) high density mainly orchards (distance between rows: 4.0-4.5 m (73.1%); distance: 1.5-3.5 (88.6%); canopy height: 3.0-4.5 (88.2%)). percentages types 77.6% 22.1% for speed (airblast sprayer) power sprayer, respectively. Spray volumes per 10a 250-300 L April, the month spraying lowest 300-400 June-August, months highest volume. Significant difference not observed conventional planting, but regional volume showed significant difference. main by using sprayers super jet nozzle (45%), wide (26%), 2-3 vertical head (25%). results will helpful establish practical agrochemicals management policy suggestion evaluation residue data efficacy data.
