Identification and Characterization of , , and Species Present in Floricultural Crops from Long Island, New York.

Several , , and species cause Pythium diseases in greenhouse floricultural crops, resulting in significant seasonal losses. Four hundred and eighteen , , and isolates from flowering crops, growing media, or bench and floor debris were collected from Long Island greenhouses or clinic samples between 2002 and 2013. Isolates were identified to species based on morphology and internal transcribed spacer barcoding.

Influence of the insecticides acetamiprid and carbofuran on arylamidase and myrosinase activities in the tropical black and red clay soils.

The objective of this study was to determine the effects of two insecticides, namely, acetamiprid and carbofuran on the enzymatic activities of arylamidase (as glucose formed from sinigrin) and myrosinase (as β-naphthylamine formed from L-leucine β-naphthylamide) in the black and red clay soils collected from a fallow groundnut (Arachis hypogaea L.) fields in the Anantapur District, Andhra Pradesh, India. The study was realized within the framework of the laboratory experiments in which the acetamiprid and carbofuran were applied to the soils at different doses (1.
