Fluorescein diacetate CAS596-09-8Also called FDA, can pass through the cellular membrane and as fluorescein accumulation in living cells. As compared with BCECF or fluorescein hydrophilic calcein low, fluorescein leakage from cells was also high. FDA is also used in flow cytometry. Fluorescence excitation and emission wavelengths are 488nm and 530nm.

FLUSILAZOLE CAS85509-19-9The three fungicides, destruction and biosynthesis of ergosterol in the cell membrane to prevent, can not be formed, the bacteria are killed. Ascomycetes, basidiomycetes and Deuteromycetes diseases caused by effective, ineffective against oomycetes, specific to the pear scab. Control of pear scab disease, in the initial spray, spray 1 times every 7 ~ 10d, 4 ~ 6 times, with 40% EC effective dose of 40 ~ 50mg/L (8000 ~ 10000 times fluid at a time), effective prevention of pear scab, and cure Pear Rust role. When disease incidence peak, spraying interval can be shortened. Can also be used for Venturia correct and powdery mildew, grape powdery mildew, leaf spot of peanut, cereal powdery mildew and eye disease, wheat glume blight, leaf rust and stripe rust, leaf spot disease of barley.
