Study On The Application Of SK Spray Oil To Ganxi-Pomelo

Ganxi-pomelo is an important kind of fruits which has large area and yield in Pinghe county of Fujian province. This paper dealt with the application of SK spray oil in flowering period,fruit period and in high-temperature phase. When the application of SK spray oil mixed with Triadimefon,Myclobutanil,Dithane M45 (Complex state Mancozeb),Wangke (Oxygen copper chloride),Kocide (Cupric hydroxide) and so on, there are some oil spots on the peel of the pomelo, which would not lead to peel burns, but would lead to serious phytotoxicity if 99% SK spray oil mixed to non-state complex Mancozeb or cuprous oxide. The experiments also showed that 99% SK spray oil or it's mixture has good results to control such pests or diseases as panonychus,scale,rust tick,macular disease and so on. It would achieve the goals of less control times and lower control cost if only use by 1-2 times per year. All these are important basises for the developmental program of the Ganxi-pomelo with using the SK spray oil all over the years.
