This position will be based in our Washington, D.C. office, although telework arrangements may be considered for the right candidate. Applicants should be experienced in all aspects of preparing, submitting, and managing applications under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), having worked for a registering entity or ...
Timings coincide with BYDV insecticide applications. Target: Winter Barley, Second Wheats and fields with variable soil types that are likely to suffer from stress in the growing season. ...
We investigated the appropriateness of several methods, including those recommended in the Aquatic Guidance Document of the European Food Safety Authority (EFSA), for the derivation of chronic Tier‐1 Regulatory Acceptable Concentrations (RACs) for insecticides and aquatic organisms. The insecticides represented different chemical classes (organophosphates, ...
In order to maintain viable harvests, oyster growers proposed the application of the neonicotinoid insecticide imidacloprid onto harvested beds for the control of burrowing shrimp. In test applications, water column concentrations of imidacloprid were relatively low and dissipated rapidly. ...
Here we explore how to use mechanistic effect models in the aquatic risk assessment of a model insecticide (Modelmethrin), applied several times per season, but rapidly dissipating between applications. ...
In order to maintain viable harvests, the oyster growers have proposed controlling the shrimp by applying the insecticide imidacloprid onto harvested beds. ESA‐listed green sturgeon forage on burrowing shrimp, and could be exposed to imidacloprid in the sediment porewater and through consumed prey. ...
These label restrictions would prohibit applications of pesticide products that EPA has identified as acutely toxic to bees, during bloom when bees are known to be present under contract. ...
Indalva S.L. is Spain's largest toll manufacturer of insecticides and herbicides, producing approximately 5,500 to 7,700 tons/yr (5,000 to 7,000 ...
Now accounting for one-third of all insecticides used globally, the neonicotinoid market was worth $2.63 billion in 2009 and is on the rise. ...

We used an IBM coupled to a toxicokinetic‐toxicodynamic model, the threshold damage model (TDM), to assess recovery times for 4 aquatic organisms, after insecticide application, in a non‐seasonal environment and in 3 spatial settings (pond, stream and ditch). ...
The use of pesticides by homeowners or pest control operators in urban settings is common, yet contributions of washoff from these materials are not easily understood. In the present study, cypermethrin, formulated as Cynoff EC (emulsifiable concentrate) and Cynoff WP (wettable powder) insecticides, was applied at typical rates to 10 different building material surfaces to examine the washoff ...
The need for locust control throughout eastern Australia during the spring of 2010 provided an opportunity to quantify residues of the organophosphorus insecticide, fenitrothion, on nymphs of the Australian plague locust, Chortoicetes terminifera Walker. Residues were collected across the different physiological states of locust nymphs observed following exposure to fenitrothion, namely live, ...
The effects of herbicide, insecticide, and fertilizer inputs on the common buttercup Ranunculus acris in field margins were studied in an experimental field study. The test design allowed us to investigate the single and combined effects of repeated herbicide, insecticide, and fertilizer applications in successive growing seasons. To assess the ...
The use of pyrethroid insecticides has increased substantially throughout the world over the past few decades as the use of organophorous, carbamate, and organochlorine insecticides is being phased out. Pyrethroids are the most common class of insecticides for ultralow‐volume (ULV) aerosol applications used to manage high ...
The authors recorded bat activity and measured pesticide residues on bat‐specific food items following applications of two insecticides in an apple orchard. High activity levels of the common pipistrelle bat, a foraging habitat generalist, were detected. ...
Insecticides are mainly used in the home environment, and most of them are recognised to pose risks for the human health. In particular, pyrethroids are an insecticide category widely used in agriculture and households, and for industrial purposes to get protection from mosquitoes, cockroaches and other insects. In this study, both exposure and risk following the ...
The following five treatments were applied under net room isolation-conditions: (i) insecticide application and release of alfalfa leafcutter bees (Megachile rotundata) during flowering; (ii) insecticide application in the absence of leafcutter bees; (iii) release of alfalfa leafcutter bees during flowering without ...
Soybean [Glycine max (L.) Merr.] production is limited in the northeastern United States so research on optimum planting date is scarce. Soybean production in this region may increase because of biodiesel demand so we initiated a 2-yr study in New York that compared soybean planting dates with and without seed-applied fungicide/insecticide treatments. Soybean planted in mid- compared with late ...
This paper reports the first three years of Bt cotton field trials, which found that Bt cotton increased cotton yields by an average of 20% and reduced insecticide applications by two-thirds. While the technical success of Bt cotton is encouraging, the tests were confined to small scale plots and unit returns found on the experiment station. ...
Western corn rootworm (Diabrotica virgifera virgifera Le Conte) is the major insect pest in the corn phase of a corn (Zea mays L.) silage–perennial forage rotation. Dairy producers may prefer seed-applied instead of soil-applied insecticides for rootworm control because of ease of use and additional control of some other soil insect pests. The objective of the 2-yr NY field study was to evaluate ...
