Abstract: A biologically pure culture of Pythium rostratum is disclosed which produces zoosporangia which produce zoospores capable of killing knapweed. Also disclosed is a method for killing knapweed, comprising: (a) growing Pythium rostratum which selectively kills knapweed on a carrier saturated with a liquid nutrient capable of supporting Pythium rostratum growth and the production of zoosporangia; and (b) applying the Pythium rostratum carrier to knapweed-infested land under moisture and temperature conditions sufficient to support Pythium rostratum growth and zoospore release by the zoosporangia, such that the zoospores are produced which are capable of killing knapweed.

Abstract: The present invention relates to a new and distinct variety of Colocasia esculenta (popularly known as taro) named ‘Pauakea’. ‘Pauakea’ differs distinctively from other taro plants by its unique combination of resistance to taro leaf blight caused by Phytophthora colocasiae, resistance to root rot caused by Pythium spp., vigorous growth, large mother corm size, and white corm of very good flour quality and good eating quality.

Abstract: The present invention relates to a new and distinct variety of Colocasia esculenta (popularly known as taro) named ‘Pa'lehua.’ ‘Pa'lehua’ differs distinctively from other taro plants by its unique combination of resistance to taro leaf blight caused by Phytophthora colocasiae, tolerance to root rot caused by Pythium spp., vigorous growth, large mother corm size, and purple corm of very good poi and eating qualities.

Abstract: The present invention relates to a new and distinct variety of Colocasia esculenta (popularly known as taro) named ‘Pa'kala’. ‘Pa'akala’ differs distinctively from other plants by its unique combination of resistance to taro leaf blight caused by Phytophthora colocasiae, high tolerance to root rot caused by Pythium ssp., vigorous growth, extra-large mother corm size, and pinkish corm of very good flour quality and good poi and eating qualities.
