Systemic application of chlorantraniliprole to cabbage transplants for control of foliar-feeding lepidopteran pests

Controle de Helicoverpa armigera (Lepidoptera: Noctuidae) em soja com inseticidas químicos e biológicos

“…Esses dados indicam reduzido tempo residual para lagartas de 2 o instar, o que pode estar relacionado à pequena área foliar do trifólio apical (ponteiro) no momento da pulverização dos tratamentos, o que determina uma pequena quantidade de inseticida depositado inicialmente nessas folhas e prejudica sua disponibilização ao longo do tempo. No entanto, no caso das diamidas, sua capacidade de translocação (Cameron et al, 2015) provavelmente possibilitou um maior aporte de inseticida às folhas apicais, a partir da calda interceptada por outras partes da planta, e contribuiu para um melhor controle de lagartas de 2 o instar a partir de 72 horas da pulverização.…”

Residual and Systemic Efficacy of Chlorantraniliprole and Flubendiamide Against Corn Earworm (Lepidoptera: Noctuidae) in Soybean

“…It is often applied to the soil as seed treatments, soil drenches, or through chemigation in multiple crops such as brassicas and other vegetables (Lahm et al 2007, Kuhar et al 2008, Palumbo 2008, Ghidiu et al 2009, Schuster et al 2009, Cameron et al 2015). With those applications, the insecticide is taken up by the roots and provides effective control of lepidopteran and other insect pests on the foliage.…”

“…With those applications, the insecticide is taken up by the roots and provides effective control of lepidopteran and other insect pests on the foliage. It is currently registered in the United States for use as an in-furrow spray at planting, transplant water treatment, hill drench at planting, surface band at planting, soil shank injection at planting, through drip irrigation, and by foliar application (Lahm et al 2007, Cameron et al 2015). Chlorantraniliprole is also effective as a seed treatment in managing Lissorhoptrus oryzophilus (Kuschel) infestations in rice, Oryza sativa (L.) (Adams et al 2016).…”

Insecticides applied to soil of transplant plugs for Bagrada hilaris (Burmeister) (Hemiptera: Pentatomidae) management in broccoli

“…Tray drenches of neonicotinoids have been effective against other pests. For instance, drenches of imidacloprid, thiamethoxam or clothianidin reduced tobacco flea beetle [Epitrix hirtipennis (Melsheimer)] feeding damage and number of green peach aphids [Myzus persicae (Sulzer)] on tobacco (Nicotiana tabacum L.) (Semtner, 2005;Semtner and Srigiriraju, 2005;Semtner and Wright, 2005;Semtner et al, 2008), while chlorantraniliprole was effective against cabbage looper [Trichoplusia ni (Hübner)] on cabbage (Cameron et al, 2015). In our study with broccoli, we also tested non-neonicotinoid systemic insecticides as tray drenches including cyantraniliprole and cyclaniliprole, as well as contact insecticides, such as flonicamid, spinetoram, tolfenpyrad, and bifenthrin, but most did not consistently affect B. hilaris damage.…”

“…Drenching seedling trays with insecticide is a precise application tactic in which the insecticide dose is placed directly onto the transplant plugs before transplanting. Previously, this technique has proven effective in managing lepidopteran and coleopteran pests of Brassica crops (Cameron et al, 2015), but little is known about how well it will control B. hilaris. Thus, the major objective of this study was to evaluate the efficacy of insecticides against B. hilaris when delivered as a seedling tray drench before planting.…”
