South Carolina Pest Management Handbook for Field Crops - 2014 CORN INSECT CONTROL Francis P. F. Reay-Jones, Extension Entomologist Grain yield reductions and losses in grain quality due to insect pests are a constant problem in the Southeast. Control options include cultural practices to prevent or avoid injury, transgenic Bt corn, at-planting insecticides (including seed treatments), and foliar insecticides. Insect pressure varies greatly from field to field. Decisions concerning pest management options should therefore be made in careful consideration of the history of insect problems in each field where corn is to be planted. Major insect pests of corn in South Carolina. Insect Description of feeding habit Methods of control Wireworms Feed on planted kernels resulting in poor germination and stunted seedlings Insecticide, tillage, control of winter weeds Cutworms Girdling of stalk at soil surface Avoid planting corn on sod or weedy land, selected Bt hybrids, insecticides Sugarcane beetles Burrow into stalk above base of roots Plant early and do not plant corn after sod Billbugs Chew into stalk and cause bud leaves to wilt and die Crop rotation, weed removal in and around corn field, insecticides Corn earworms Feed on leaves in whorl and on ear tissue near ear tip Insecticides, selected Bt hybrids, plant early Fall armyworms May feed on all above ground parts of corn plant Bt hybrid, insecticides, plant and harvest early, control grassy weeds Lesser cornstalk borers Tunnel into corn seedling Crop rotation and early planting, selected Bt hybrids, insecticides Several types of Bt corn are available, each characterized by an ‘event’ (i.e. a successful insertion of the genetic package into a plant) and cry proteins. In a nutshell, there are Bt traits for above-ground pests, Bt traits for rootworms and stacked Bt traits for both above-ground pests and rootworms. Please refer to table below for efficacy of available products. Bt traits for above-ground pests. - Herculex I (event TC1507, cry protein Cry1F). Optimum Intrasect (events TC1507 and MON810, cry proteins Cry1F and Cry1Ab). YieldGard CB (event MON810, cry protein Cry1Ab). Genuity VT Double Pro (event MON89034, cry proteins Cry1A.105 and Cry2Ab2). Agrisure CB/LL (event Bt11, cry protein Cry1Ab). Agrisure Viptera 3110 (events MIR162 and Bt11, vip protein Vip3A and cry protein Cry1Ab). 43 South Carolina Pest Management Handbook for Field Crops - 2014 All products provide excellent control of stalk borers (European corn borer, southern cornstalk borer). The activity in seedling and whorl stage is greater in Herculex I, which provides good early season control of cutworms, lesser corn stalk borer, and fall armyworm. YieldGard CB and Agrisure CB/LL have fair activity for corn earworm infestations in corn ears, whereas control with Herculex I is poor. A more recent Bt corn product is Genuity VT Double Pro. This is the first Bt corn to have two genes expressing Bt toxins to control above ground Lepidopteran pests. The major advantage relative to the previously mentioned products is that it provides very good control of both corn earworm and fall armyworm. The new Viptera trait will also provide excellent control of corn earworm and fall armyworm, and good control of cutworms. These hybrids may be particularly useful in late planted and no-till corn. Bt traits for rootworms. - Herculex RW (event DAS59122-7, cry protein Cry34/35Ab1). YieldGard Rootworm (event MON863, cry protein Cry3Bb). YieldGard VT Rootworm/RR2 (event MON88017, cry protein Cry3Bb). Agrisure RW (event MIR604, cry protein mCry3A). All products provide control of western corn rootworms (but no control of grubs and wireworm). Western corn rootworms are not currently widespread pests in South Carolina, and these products should generally not be needed. Stacked Bt traits for above-ground pests and rootworms. - Herculex XTRA (events TC1507 and DAS59122-7, cry proteins Cry1F and Cry34/35Ab1). YieldGard Plus (events MON810 and MON863, cry proteins Cry1Ab and Cry3Bb). YieldGard VT Triple (events MON810 and MON88017, cry proteins Cry1Ab and Cry3Bb1). Agrisure CB/LL/RW (events Bt11 and MIR604, cry proteins Cry1Ab and mCry3A). Agrisure GT 3000 (events Bt11, and MIR604, cry proteins Cry1Ab and mCry3A). Agrisure Viptera 3111 (events MIR162, Bt11 and MIR604, vip protein Vip3A and cry proteins Cry1Ab and mCry3A). Genuity VT Triple Pro (events MON89034 and MON88017, cry proteins Cry1A.105, Cry2Ab2 and Cry3Bb1). Genuity SmartStax (events MON89034, MON88017, TC1507 and DAS59122, cry proteins Cry1A.105, Cry2Ab2, Cry3Bb, cry1F, and Cry34/35Ab1). These products combine the cry proteins (and efficacy) of the above-ground pest and rootworm Bt corn traits. Refuge requirements for Bt corn for above-ground pests in Cotton Belt (see dealers for complete refuge requirements) - For YieldGard Corn Borer, and Agrisure CB/LL, Herculex I: 50% of corn on a farm can be planted as Bt corn. Genuity VT Double Pro, Agrisure Viptera 3110, and Optimum Intrasect: 20% of corn on a farm can be planted as Bt corn. Blocks can be internal (within Bt field) or external (in separate field within ½ mile of Bt field to maximize random mating; ¼ mile is however preferred. In field strips: at least 4 rows wide to reduce effect of larval movement (6 rows preferred) Refuge can be sprayed with any insecticide except Bt products 44 South Carolina Pest Management Handbook for Field Crops - 2014 Refuge requirements for Bt corn for rootworms in Cotton Belt (see dealers for complete refuge requirements) Bt corn for rootworm has specific regulations that differ from stalk borer Bt corn (see http://www.epa.gov/oppbppd1/biopesticides/pips/bt_corn_refuge_2006.htm for EPA requirements). The major difference for rootworm Bt corn is that refuges must be either adjacent to or within the Bt field, rather than within ¼ mile of the Bt field for stalk borer Bt corn. This is due to the poor flight ability of corn rootworm adults. Refuge requirements for stacked Bt corn for above-ground pests and rootworms in Cotton Belt (see dealers for complete refuge requirements) - - For YieldGard Plus, YieldGard VT Triple, Agrisure CB/LL/RW, Agrisure GT 3000, and Herculex Xtra: 50% of corn on a farm can be planted as Bt corn. Genuity VT Triple PRO, Genuity SmartStax, Agrisure Viptera 3111: 20% of corn on a farm can be planted as Bt corn. 2 options for the refuge: o Common rootworm/corn borer refuge o Discrete rootworm and corn borer refuges For common refuge and discrete rootworm refuge: use adjacent field, block perimeter, or in-field strip. For discrete corn borer refuge: separate fields can be used in addition to other refuge options. For shared refuge and discrete rootworm refuge: refuges must be adjacent to or within field. For discrete corn borer refuge: separate refuges must be within 1/2 mile (but 1/4 mile preferred). At least 4 rows (for discrete corn borer refuges, at least 6 rows are recommended). Refuge can be sprayed with any insecticide except Bt products. 45 Relative Efficacy of Various Bt Corn Products1.

Southern corn rootworm is the most prevalent species. These “rootworm” products are not effective against southern corn rootworm. They are effective against western corn rootworm larvae, which occur in areas such as north Alabama and north Georgia 4 Based on limited data 5 Lepidopteran Bt traits do not specifically list lesser cornstalk borer as a target pest 6 See product Insect Resistance Management (IRM) documentation from the seed companies for more details. 7 The meaning of these terms is somewhat arbitrary. Excellent usually means better than 95 percent control. Poor means about 30% control. Rankings are meant to be relative.
