petunia axillaris/抗真菌药

In April 2001, late blight was detected on petunia (Petunia × hybrida Hort.) in a glasshouse in central Maryland. Symptomatic plants had extensive light gray, irregularly shaped, slightly sunken lesions up to 3 cm long on upper leaves and branches. Stems were distorted or dead above points where

Botrytis cinerea infects most major greenhouse crops worldwide. With its increasing resistance to conventional fungicides and the movement of the greenhouse industry toward more sustainable production practices, alternative methods of control are needed. The objective of this study was to

A blight (wet rot) of petunia (Petunia ×hybrida Hort. Vilm.-Andr.) was observed in a wholesale propagation nursery in Baton Rouge, LA in September 2002. The grower reported that plants wilted and then completely rotted. The disease occurred during a period of hot, humid, and cloudy weather.

Factors affecting the management of petunia and tomato late blight, caused by Phytophthora infestans, under greenhouse conditions were investigated. Late blight-infected petunias (Petunia × hybrida) and tomatoes (Lycopersicon esculentum) each produced sporangia that were dispersed throughout the

The structure of a novel plant defensin isolated from the flowers of Petunia hybrida has been determined by (1)H NMR spectroscopy. P. hybrida defensin 1 (PhD1) is a basic, cysteine-rich, antifungal protein of 47 residues and is the first example of a new subclass of plant defensins with five
