Seven fluorescent Pseudomonas spp. capable of inhibiting reproduction of Mesocriconema xenoplax have been isolated from soil sites that suppress both nematode multiplication and Peach Tree Short Life (PTSL). One of these seven strains, Pseudomonas sp. BG33R, inhibits M. xenoplax multiplication in vivo and egg hatch in vitro. Mesocriconema xenoplax populations on peach seedlings inoculated with ...

I t is the purpose of this report to present quantitative data on some effects of high light intensities on Chlorella. No comparable data have as yet been published, although a number of workers, using various techniques, have studied the effects of intense light on the green plant. I t has been generally demonstrated that after long exposure of a plant to strong light there may be a disappeara...

The European legislative on the use of different control strategies against plant-parasitic nematodes, with particular reference to pesticides, is constantly evolving, sometimes causing confusion in sector operators. This article highlights nematode management allowed C Zone Union, which includes chemical nematicides (both fumigant and non-fumigant), agronomic (crop rotations, biofumigation, co...
