Pythium aphanidermatum Causing Collar Rot on Papaya in Baja California Sur, Mexico

The Degeneration of Cardon Populations in Baja California Sur, Mexico

Identifying recharge from tropical cyclonic storms, Baja California Sur, Mexico.

Groundwater in the Todos Santos watershed in southern Baja California, and throughout the peninsula south of latitude 28°N, has values of (δ18 O‰, δD‰) ranging between (-8.3, -57) and (-10.9, -78). Such negative values are uncharacteristic of the site latitude near the sea level. Altitude effects do not explain the isotope data. Tropical depressions originating along the Pacific coast of North ...

Timing Pseudomonas chlororaphis applications to control Pythium aphanidermatum, Pythium dissotocum, and root rot in hydroponic peppers

The ability of the microbial agent Pseudomonas (Ps.) chlororaphis Tx-1 to suppress Pythium aphanidermatum and Pythium dissotocum, and control root rot, was investigated as a function of time of agent application and pathogen inoculation in vegetativestage sweet peppers grown in single-plant hydroponic units. The agent was applied to the nutrient solution at 1 10 CFU/mL and roots were inoculated...

A new species of Modisimus Simon (Araneae: Pholcidae) in Baja California Sur, Mexico.

The genus Modisimus Simon 1893 (Pholcidae) is distributed across the Americas from Venezuela to the USA, including the Caribbean Antilles, with an endemic species in the Galapagos Islands and one cosmopolitan species (World Spider Catalog 2015). Until now, 81 species of Modisimus have been described, of which 17 species are found in Mexico (World Spider Catalog 2015). In this paper, a new Mexic...

Effect of Chitosan on Rhizome Rot Disease of Turmeric Caused by Pythium aphanidermatum

Chitosan was evaluated for its potential to induce antifungal hydrolases in susceptible turmeric plant (Curcuma longa L.). Under field conditions, the application of chitosan (crab shell) to turmeric plants by foliar spray method induces defense enzymes such as chitinases and chitosanases. Such an increase in enzyme activity was enhanced by spraying chitosan (0.1% w/v) on leaves of turmeric pla...
