Reducing Phosphorus Losses from Surface-Irrigated Fields: Emerging Polyacrylamide Technology

Most P losses from surface-irrigated fields occur via runoff, are associated with eroded sediment, and can be minimized by eliminating irrigation-induced erosion. A convenient new practice that eliminates furrow irrigation-induced soil losses uses a high molecular weight, anionic polyacrylamide (PAM) applied to initial irrigation inflows. We hypothesized that, compared to control furrows, PAM t...

Effects of Bacillus thuringiensis on non-target herbivore and natural enemy assemblages in tropical irrigated rice.

Endotoxins from Bacillus thuringiensis (Bt) produced in transgenic pest-resistant Bt crops are generally not toxic to predatory and parasitic arthropods. However, elimination of Bt-susceptible prey and hosts in Bt crops could reduce predator and parasitoid abundance and thereby disrupt biological control of other herbivorous pests. Here we report results of a field study evaluating the effects ...

Mosquitoes and malaria transmission in irrigated rice-fields in the Benoue valley of northern Cameroon.

Africa has a very high human population growth rate which is not matched by the rate of increase in agricultural production per capita. One solution often envisaged is to increase of the area of irrigated land, permitting two crops per year. The most extensively irrigated crop is rice, for which demand continues to increase. Rice-fields are usually flooded for long periods, providing suitable b...

Impact of lambdacyhalothrin on arthropod natural enemy populations in irrigated rice fields in southern Brazil

The present study aimed to determine the selectivity of the pyrethroid lambdacyhalothrin on arthropod natural enemy populations in irrigated rice fields in Rio Grande do Sul, Brazil. The study was conducted at three sites: districts of Cachoeira do Sul, Eldorado do Sul and Capivari do Sul during the crop years of 2007/2008 and 2008/ 2009. Each site consisted of two subareas divided into four pl...

Conservation implications of flooding rice fields on winter waterbird communities

The effects of flooding harvested rice fields on waterbird communities were studied during winter. Variation in the number of waterbird species, overall densities of all waterbirds, wading birds, waterfowl, and shorebirds, and a measure of conservation value that weighted species according to their relative abundance and population trends were examined. Each variable was tested for differences ...
