Dicamba volatility in humidomes as affected by temperature and herbicide treatment

Activity of eleven enzymes in nymphs of Lipaphis erysimi as affected by 2,4-D (herbicide) treatment

The activity of eleven enzymes involved in development, ageing and in metabolism of xenobiotics in insects, was investigated under the influence of 2,4-D (2,4-Dichlorophenoxyacetic acid), in the mustard aphid, Lipaphis erysimi (Kaltenbach) (Rhynchota Aphididae), after treating the 2 instar nymphs for 13, 25 and 37 h. Studies of two hydrolases and one group transfer enzyme revealed significant e...

Propagation of Sound as Affected by Wind and Temperature Gradients

Herbicide leaching as affected by macropore flow and within-storm rainfall intensity variation: a RZWQM simulation.

Within-event variability in rainfall intensity may affect pesticide leaching rates in soil, but most laboratory studies of pesticide leaching use a rainfall simulator operating at constant rainfall intensity, or cover the soil with ponded water. This is especially true in experiments where macropores are present--macroporous soils present experimental complexities enough without the added compl...

Phototropic Circus Movements of Limax as Affected by Temperature

1. The theory of animal phototropism requires for particular instances a knowledge of the action of light as exerted through each of two bilaterally located receptors functioning singly. The measurement of "circus movements" which this involves must be concerned with such aspects of the reaction as are demonstrably dependent upon the effect of light. 2. The negatively phototropic slug Limax max...

Glyphosate and dicamba herbicide tank mixture effects on native plant and non-genetically engineered soybean seedlings.

Crops engineered to contain genes for tolerance to multiple herbicides may be treated with several herbicides to manage weeds resistant to each herbicide. Thus, nearby non-target plants may be subjected to increased exposure to several herbicides used in combination. Of particular concern are native plants, as well as adjacent crops which have not been genetically engineered for tolerance to he...
