Alternative Agents for Control of European Corn Borer and Corn Flea Beetle on Sweet Corn

Abstract

ABSTRACT. Small plot field trials were conducted in 2002 and 2003 to compare European corn borer (ECB) (Ostrinia nubilalis Hübner) control

ROS‐Inducible DNA Cross‐Linking Agent as a New Anticancer Prodrug Building Block

“…Although in 2006 the mixture of organophosphate and pyrethroid showed a lower ECB severity than oxadiazine insecticide in late applications (T4), the two insecticides tested in the experiment did not show any significant differences in their efficacy to control fungal ear rot or fumonisin contamination for the different application timings. Indoxacarb has greater ovicidal properties,32 while a mixture of clorpirifos and cypermethrin may have a higher contact and residual activity on neonates;33 however, when they were applied at the same time, they led to a similar control of ECB damage and fumonisin content, as reported in a previous work16 and confirmed by Bailey et al 34 and Bažok et al 35 Thus these data underline that application timing is more important than the type of insecticide applied.…”

Contact and oral toxicity to honey bees (Apis mellifera) of agents registered for use for sweet corn insect control in Ontario, Canada

“…Sweet corn genetically engineered to express the Bt endotoxin Cry1AB is as effective for ECB control as the registered insecticides (Bailey et al, 2005). Tassels and pollen from Bt sweet corn caused no significant honey bee toxicity in other larval feeding studies (EPA, 2000).…”

“…Recently registered insecticides such as spinosad (SUCCESS ® 480SC), clothianidin (PONCHO ® 600F), and sweet corn genetically engineered to express Bacillus thuringiensis Berliner (Bt) endotoxin Cry1AB (ATTRIBUTE  ) have been reported to effectively control ECB and CFB (Burkness et al, 2001;Andersch and Schwarz, 2003;Bailey et al, 2005). To investigate the potential risk associated with use of carbofuran, lambda-cyhalothrin, imidacloprid, clothianidin, spinosad and Bt-sweet corn, we assessed the direct, residual contact and oral toxicities of these pest control agents to honey bees.…”

Simultaneous Determination of Six Insecticides in Okra (Abelmoschus esculentus L. Moench) by UHPLC-MS/MS

“…Thiamethoxam is a second-generation neonicotinoid; it belongs to the thianicotinyl subclass that interferes with the nicotinic acetylcholine receptors in the insect's nervous system, it has systemic and residual activity in several crop plants against broad range pests [5]. Clothianidin, the newest member of the chloronicotinyl insecticide family, it has a high activity against a broad range of insects, including sucking insects, chewing insects, and some lepidopterans [6]. Flonicamid can be against to the aphids and other sucking insects and whiteflies, and other pests [7].…”
