摘要
粉锈宁拌种是小麦白粉病应急防治的关键技术之一。本文通过小区、大田系统观察及大面积示范，系统分析并建立流行速率的数学模型，进一步阐明了粉锈宁拌种在防治秋苗感病、压低早春菌源基数、降低流行速率、控制小麦白粉病大范围流行中的重要作用。
Wheat seed-treated With triadimefon is one of the most important measures to control powdery mildew of Wheat. ThiS paper systematically analyzed and Set up a set of mathematical models of epidemic rate through plot trials,systematical observations and demonstration in large field,and elucidated the effection of seed-treated with triadimefon on controlling powdery mildew prevailing in autumn seedlings,abating population in early spring,decreasing epidemical rate and controlling powdery mildew in a large scale.
