Potential of Weed Extracts to Control Bacterial Blight Disease

Potential of Weed Extracts to Control Bacterial Blight Disease Caused by Xanthomonas oryzae pv. Oryzae in Rice. This study aimed to find out the potential and effectivity of weed extracts to control bacterial blight disease caused by Xanthomonas oryzae pv. oryzae in rice. The experimentation process has four stages. In preparing the medium, 300 g of sliced unpeeled potato was boiled and 24 g agar, 0.5 g K[4]HPO[4], 0.5 g CaCO[3], 0.5 g NaCl, 5 g peptone and 20 g sucrose were melted.

Cacao Seeds as Regulator of Angiogenesis in Duck Embryos

This research was conducted to determine the ability of “cacao” (Theobroma cacao) seed nicotinamide component to regulate angiogenesis or process of blood vessel formation in duck embryos. Abnormalities in angiogenesis are linked to the development of diseases such as cardiovascular ailments in case of insufficient blood vessel growth and cancer in case of excessive development. Varying "cacao" seed solutions were introduced into the chorion of duck embryos prior to the period of blood island formation.

Plants Extracts as Control Agents of Braconid

Selected Plants Extracts as Control Agents of Braconid sp. Corcyra cephalonica Stn. is used as a fastidious host in the production of Trichogramma sp. It is a stored grain pest with the common name rice grain moth which can be found in corn/rice mills. It is easy to handle and can be mass produced in the laboratory. The mass production of Trichogramma sp., a biological control agent of lepidopterous pests is dependent on the abundance of Corcyra cephalonica Stn.

Rapid In-Vivo Propagation of Curcums Using Stem Cuttings grown in Different Media

The In Vivo propagation of Curcums (Z. spectabile) using stem cutting grown in different media was investigated at Central Mindanao University, Musuan, Bukidnon from June 15 to September 30, 2005. The study was conducted in a 3 x 4 factorial arrangement in a Completely Randomized Design replicate thrice with five samples per replicate. Three stem cutting sections: basal, middle and tip served as factor A and five growing media: garden soil, sand plus rice hulls, garden soil plus sand, and rice hulls plus sand as factor B.
