Abstract

There is a need to identify combination treatments with high efficacy against Phytophthora capsici, a serious pathogen of chile pepper (Capsicum sp.) and other vegetable crops in New Mexico and worldwide. A greenhouse study was conducted to determine the effects of seed, plant, and soil treatment with selected commercial formulations of Bacillus and Streptomyces, and chemical fungicides (mefenoxam) on infection of chile pepper by P. capsici. The area under disease progress curve (AUDPC) was evaluated under seed treatment used in conjunction with soil treatment, and plant treatment used in conjunction with soil treatment. There was no significant interaction (P > 0.05) between seed treatment and soil treatment, and between plant treatment and soil treatment. Soil treatment with mefenoxam reduced AUDPC over 50% compared to control (untreated). Percent plant stand and percent plant survival were greater in soil treated with mefenoxam, Streptomyces lydicus, and S. griseoviridis than in untreated soil. [ABSTRACT FROM AUTHOR]

14. Natural Law, Santa Clara, and the Supreme Court.

Author

Rodgers, Raymond S. and Lujan, Phillip

Abstract

The court case, "Santa Clara Pueblo, et al. v. Julia Martinez, et al.," is the subject of this paper. It gives the background of the case of a woman whose children were refused admittance to tribal rolls because of an ordinance prohibiting the enrollment of children whose father is not a tribal member. The paper gives the arguments of representatives of the Pueblo perspective and of the Anglo perspective, both of which appeal to natural law: the tribe's claim to the right to decide its own membership and the plaintiff's invocation of the right to equal protection under the law. The paper concludes with the philosophical and intercultural implications of the Supreme Court's ruling in the case, which was that tribal sovereignty affords immunity to the tribe from federal suits.
