“…Primisulfuron toxicity to Z. mays has likewise been shown to be increased by insecticides (Biediger et al 1992;Kwon et al 1995). In all cases, the increased phytotoxicity is attributed to inhibition by the insecticide of the cytochrome P 450 monooxygenases involved in the metabolism of the herbicides (Baerg et al 1996;Frazier et al 1993;Kreuz and Fonne Pfister 1992;Kwon et al 1995;Moreland et al 1993). Simpson et al (1994) reported that application of 2,4-D to Z. mays overcame much of the phytotoxicity from a nicosulfuron plus terbufos combination as 2,4-D increased the ability of Z. mays to metabolize the herbicide.…”

Interactions between weeds, arthropod pests, and their natural enemies in managed ecosystems

Interactions between weeds and arthropods occur frequently. This review covers the topic of weed/arthropod interactions, and provides the reader with access to literature in the subject area that is scattered in weed science, entomological, crop production, and ecological journals. We first analyze the current status of weed and arthropod management in the context of multidisciplinary integrated pest management (IPM). The remainder of the review is organized according to the mechanisms driving interactions. The first section deals with interactions driven by trophic relationships, and is subdivided into direct and indirect trophic interactions. Direct trophic interactions occur when pest or beneficial arthropods feed directly on weeds. Indirect trophic interactions occur when arthropod feeding damage to crops impacts weeds through alteration of ecosystem resource availability, or through weeds serving as hosts for alternate prey for beneficial arthropods, or via tritrophic interactions. The second mechanism driving interactions is considered in relation to alteration of the physical habitat by the presence of weeds, such as alteration of temperature within the plant canopy. The third major mechanism driving interactions is based on control tactics for the two types of pests. These are considered from the aspect of direct physical effects, such as tillage, and from the aspect of interactions resulting from the use of pesticides. The latter is divided into direct effects of herbicides and insecticides on non-target pests and beneficials, and on interactions that result from alteration of host plant physiology by pesticides. A conclusion section attempts to place the impact of interactions into an IPM framework, and to indicate where multidisciplinary research involving weed and arthropod management should be focused in the future.

“…Herbicide‐insecticide interactions have the potential to cause corn ( Zea mays L.) injury and yield loss. For example, the use of organophosphate (OP) soil insecticides in combination with sulfonylurea herbicides results in corn injury and yield losses up to 54% (2,5,6,8,9,10). OP insecticides reduce the rate at which the cytochrome P450 enzyme metabolizes sulfonylurea herbicides, resulting in a higher concentration of the herbicide remaining in the plant longer than if no insecticide was used (1,4).…”

Mesotrione is a selective herbicide used for preemergence and postemergence weed control in corn. A better understanding of the interactions between mesotrione and soil insecticides is needed to avoid risk of serious corn injury. Field trials were conducted to examine corn injury from mesotrione applied postemergence as affected by insecticide type, application method, and application rate. Corn injury from mesotrione applied postemergence at 0.19 lb ai/acre was 34, 19, and 13% in corn treated with terbufos, chlorpyrifos, and tefluthrin, respectively. In a separate study, corn injury was greater in corn treated with terbufos than clorpyrifos. Injury from mesotrione increased when terbufos was applied at two times the typical rate. Corn injury was higher when terbufos was applied in‐furrow versus T‐band. In each study, corn recovered rapidly from mesotrione injury with no reduction in corn yield. The extent of corn injury observed in these trials indicate that the combination of foliar‐applied mesotrione following soil‐applied terbufos should be avoided.

“…Foliage and root injury, reduced height, and grain yield loss were observed. The insecticide appears to interfere with the plants ability to metabolize the herbicide (Frazier et al 1993). The insecticide malathion has been shown to increase cotton injury when applied in combination with pyrithiobac (Allen and Snipes 1995;Snipes and Seifert 2003).…”

Pyrithiobac and Insecticide Coapplication Effects on Cotton Tolerance and Broadleaf Weed and Thrips (Frankliniellaspp.) Control

Field studies investigated possible interactions associated with early-season coapplication of the herbicide pyrithiobac and various insecticides. Pyrithiobac at 70 g ai/ha, in combination with the insecticides acephate or dicrotophos at 370 g ai/ha, fipronil at 56 g ai/ha, imidacloprid at 52 g ai/ha, lambda-cyhalothrin at 37 g ai/ha, or oxamyl, carbofuran, or dimethoate at 280 g ai/ha did not reduce cotton leaf area, height, main stem node number, main stem nodes to first square, days to first square or flower, main stem nodes above white flower, or seed cotton yield compared with pyrithiobac alone. Pyrithiobac alone reduced dry weight of pitted morningglory, hemp sesbania, prickly sida, velvetleaf, and entireleaf–ivyleaf morningglory 28 d after treatment (DAT) 86, 98, 51, 94, and 91%, respectively, and weed control was not affected by the coapplication of insecticides. Control of thrips (adult plus larvae) 5 DAT with insecticides was unaffected by pyrithiobac addition at the P = 0.05 level of significance. At the P = 0.1 level, however, addition of pyrithiobac to dimethoate resulted in a reduction in insecticide efficacy in one of three experiments. Efficacy of other insecticides was unaffected.
