Resting propagules are comparatively large and heavy, and as such they don't disperse as well as other spore types such as sporangia or zoospores
(Judelson and Blanco 2005).
We transferred fresh grass blades, with [greater than or equal to] 10 vesicles per blade containing numerous zoospores
, to the plates holding 5 mosquito larvae per well (total of 30 larvae per plate).
Once the fungus's life cycle is complete; each sac-like structure produces a pinhead-size discharge tube, This tube pokes through the tadpole's skin, releasing tens to hundreds of zoospores
into the water.
Diquat and glufosinate are not recommended with adjuvants either, as this may jeopardise crop safety and efficacy, but they can and should be mixed with blight fungicides with known zoospore
activity, especially when used in a split dose sequence," concludes Andy Leader.
5) Sporophylls with sori over all of the sporophylls surface releasing zoospores
Remaining aliquots were determined for direct count of protozoa, and fungal zoospores
according to the methods described by Galyean (1989) using a haemocytometer (Boeco, Singapore), and three groups of bacteria (cellulolytic, proteolytic, and amylolytic bacteria) were determined using roll-tube technique (Hungate, 1969).
In addition to low nutrient level affected by the Kuroshio current, abiotic factors such as suspended and deposited particles that have a lethal effect on survival of zoospores
, and germination and gametophyte of E.
Factors influencing sporangial formation and zoospore
activity in Phytophthora parasitica v.
Perkinsus marinus has a nonphotosynthetic plastid in the biflagellate zoospore
stage (Perkins 1996).
Induction of zoospore
formation in Thai isolates of Pythium insidiosum.
Effect of phosphite on in planta zoospore
production of Phytophthora cinnamomi.
The inoculum was maintained on ice to delay zoospore
release until after inoculation and to ensure a uniform sporangial concentration with time (Jones et al.
