用固定翼飞机和小容量地面空气喷淋机对同一果园场地施用西维因、上尉或两者并用。在两年的时间里，总共提出了8项申请，其中4项通过空中设备，4项通过地面设备。对两个气候参数的影响进行了评价。第一次是在相对平静的条件下出现逆温，第二次没有逆温，风速高达12.9 km/h。无论风或大气稳定性如何，在最远的采样距离（下风500米）发现了空中施用的西维因沉积物。在类似条件下的地面应用，在温度反演期间在150米处留下了沉积物，但在没有反演的情况下，在50米或更远的地方没有检测到沉积物的水平。船长漂移之间的差异没有明确界定；一般说来，船长似乎不象西威因那样容易随波随流。
Applications of carbaryl, captan, or both were made by fixed-wing aircraft and by low-volume ground air blast sprayer to the same orchard site. Over the course f 2 years, a total of eight applications was made, four by air and four by ground equipment. The effect of two climatic parameters was evaluated. The first was under relatively calm conditions with a temperature inversion present and the second without a temperature inversion and with wind movement up to 12.9 km/h. Regardless of wind or atmosphere stability, carbaryl deposits from aerial application were found at the furthest sampling distance (500 m downwind). Ground applications under similar, conditions left deposits at 150 m during a temperature inversion but provided no detectable levels at 50 m or further in the absence of an inversion. Differences between captan drift were not as clearly defined; generally, captan did not appear to drift as readily as carbaryl.
