Los Oomycetes son un grupo de organismos que alberga géneros y especies destructivas plantas cultivadas silvestres. En México, especialmente en el Estado Sinaloa, la información sobre esos su presencia aguas superficiales empleadas para uso agrícola es escasa. Esta investigación se realizó con objetivo determinar del género Pythium irrigación Valle Culiacán, México. De septiembre 2018 a enero 2...

The objectives were to evaluate the effects of increasing metal micronutrient concentrations and silicon (Si) on plant growth susceptibility Pythium root rot with hydroponically grown lettuce (Lactuca sativa). In first experiment, was in hydroponic solutions micronutrients iron (Fe), manganese (Mn), copper (Cu), zinc (Zn) supplied at either 0, 2.5, 5, or 10 mg∙L−1. A standard commercial solutio...

Pilasporangium apinafurcum, formerly classified as Pythium apinafurcum, is a unique oomycete that infects plants asymptomatically. Here, we present the draft genome sequences of two variants of P. apinafurcum, JCM 30513 and JCM 30514, isolated from uncultivated field soil in Wakayama Prefecture, Japan.

A survey of ticks and other ectoparasites was carried out during a national biodiversity scientific expedition at Gunung Stong Forest Reserve, Kelantan, Malaysia from 23-29 May 2003. A total of 272 animals comprised of 12 species of birds, 21 species of bats, 7 species of rodents and 2 species of insects were examined for ticks and other ectoparasites. From these animals, 5 species in 4 genera ...

Phylogenetic relationships among 50 Phytophthora species and between Phytophthora and other oomycetes were examined on the basis of the ITS sequences of genomic rDNA. Phytophthora grouped with Pythium, Peronospora, and Halophytophthora, distant from genera in the Saprolegniales. Albugo was intermediate between these two groups. Unlike Pythium, Phytophthora was essentially monophyletic, all but ...

Principally, plants grown in soilless culture may be attacked by the same pests and diseases as cultivated traditionally in soil. The most destructive phytopathogens are fungi, such as Phythium, Phytophthora and Fusarium, followed by viruses, bacteria and nematodes. We investigated effect of carbon nanotube filters on disease management of soilless culture. Tomato seedlings transplant in plasti...
