25. Fungal β-Tubulin, Expressed as a Fusion Protein, Binds Benzimidazole and Phenylcarbamate Fungicides
Benzimidazoles are important antitubulin agents used in veterinary medicine and plant disease control. Resistance is a practical problem correlated with single amino acid changes in β-tubulin and is often linked to greater sensitivity to phenylcarbamates. This negative cross-resistance creates opportunities for durable antiresistance strategies. Attempts to

26. Sub-lethal effects of a copper sulfate fungicide on development and reproduction in three coccinellid species.
Copper-based fungicides reliably control various foliar diseases in citrus production, although they are suspected to exacerbate mite problems through various mechanisms. Studies have shown negative effects of various copper formulations on entomopathogenic fungi, nematodes, and parasitoids, but few have sought to measure its impact on the biology of predato

27. Role of copper resistance in competitive survival of Pseudomonas fluorescens in soil.
A copper-resistant strain (09906) of Pseudomonas fluorescens that was isolated from a citrus grove soil is being investigated as a biological control agent for Phytophthora root rot. Since citrus grove soils in California are often contaminated with copper from many years of copper fungicide applications, the role of copper resistance in survival of strain 0

28. Responses of two ladybeetles to eight fungicides used in Florida citrus: Implications for biological control
Two ladybeetles, Cycloneda sanguinea and Harmonia axyridis, were exposed in the laboratory to eight fungicide formulations commonly used in citrus production in Florida. Both benomyl and the combination of copper and petroleum oil proved toxic to larvae of C. sanguinea that were exposed to concentrations corresponding to recommended field rates, either as le
