| At what stages of growth are corn plants most susceptible to infestation by stalk borer larvae, and what types of damage can they cause?Corn plants are most susceptible to infestation by stalk borer larvae at the V1-V5 stages, which corresponds to a plant height of about 2 to 24 inches. The larvae can damage corn by defoliating leaves and burrowing into stalks. While feeding on leaves does not typically cause economic damage, larvae can clip newly emerging plants, potentially causing death.

This internal feeding protects the larvae from insecticidal treatments, rendering such applications ineffective once the larvae have tunneled into the stalk. |

| What impact does stalk borer infestation have on corn plants, and how can the likelihood of infestation be reduced?Stalk borer infestation can cause significant damage to corn plants by shredding the leaves and destroying the growing point, which can result in a condition known as dead heart where the outer leaves appear healthy but the newest whorl leaves die, potentially leading to barren plants. The likelihood of infestation can be reduced by controlling weeds, especially giant ragweed, around cornfields during August and September, as female moths prefer to lay eggs in weedy areas during this time.flagging or dead heart). A dead heart plant will have outer leaves that appear healthy, |
| but the newest whorl leaves die and can cause barren plants. |

| point. |
| Stalk borer infestations are more likely in corn surrounded by giant ragweed. Female |
| moths prefer to lay eggs in weedy areas in August and September, so minimizing |
| weeds in and around corn during that time will discourage egg-laying. UsingStalk borer infestation in corn plants leads to significant damage as the larvae bore into the stems, causing the plants to wilt and often die. This can drastically reduce crop yields. To decrease the chances of infestation, it is crucial to implement integrated pest management (IPM) strategies. These include monitoring fields with persistent infestations annually, controlling grassy edges around corn fields to deter egg-laying by mated females in the fall, and applying herbicides to kill spring weeds, which may otherwise drive larvae to young corn plants. Foliar insecticide applications should target larvae as they migrate from grasses to corn, rather than applying insecticides to infested corn, which is ineffective once larvae have tunneled into the stalk. |

| Long term management requires controlling grassy edges around corn so that mated |
| females will not lay eggs in that area during the fall.Herbicides can indirectly affect stalk borer larvae by eliminating spring weeds, which are the initial hosts for the larvae after hatching. When these weeds are killed, the larvae are forced to migrate and may infest young corn plants. For long-term management of stalk borers, it is recommended to control grassy edges around corn fields. This is because mated females tend to lay eggs in these areas during the fall. By managing these peripheral grassy areas, the likelihood of egg-laying in proximity to corn fields is reduced, thereby decreasing the potential for future infestations. |

| How far into corn rows do the larvae typically move, and what are the signs of their infestation?The larvae typically only move into the first four to six rows of corn. Signs of their infestation include new leaves with irregular feeding holes, small larvae resting inside the corn whorls, and the presence of frass pellets in the whorl or at the entry hole in the stalk. Young corn is particularly vulnerable to severe damage, but plants are unlikely to be killed once they reach the V7 growth stage, which is characterized by seven true leaves.number of plants infested. The larvae are not highly mobile and typically only move |

| amount of frass pellets in the whorl or at the entry hole in the stalk. Young corn is |

The signs of infestation include defoliation of leaves and more critically, the burrowing of larvae into stalks. While defoliation itself does not usually result in economic damage, the larvae can clip newly emerging plants, potentially causing plant death. The most significant damage occurs when larvae enter the stalk and destroy the growing point, which can kill the corn plants. It is important to note that about 10 percent of stalk borer larvae begin moving to corn after accumulating 1,300 to 1,400 degree days. |

| The economic threshold developed by ISU entomologist Larry Pedigo assists in controlling stalk borer larvae in corn by helping to determine when insecticide treatments are justifiable. This decision is based on the market value of the crop and the stage of the plant, with young plants having a lower threshold due to their increased vulnerability to damage from stalk borer larvae. The threshold is detailed in Table 1, which outlines the economic thresholds for stalk borer in corn according to plant stage, expected yield, and market value.Control. To prevent stand loss, scout and determine the percent of infested plants. |

The documents do mention the existence of an economic threshold table (Table 1) that was developed to help determine justifiable insecticide treatments based on market value and plant stage. However, the specific values and parameters of this threshold are not included in the context provided. To obtain the precise economic thresholds, one would need to refer to the original source or the table mentioned. |

| According to the Integrated Crop Management article, if an insecticide is warranted to control stalk borer infestations, it can be tank-mixed with a fast burndown herbicide or applied seven days after a slow burndown herbicide. Border treatments are recommended if infestations are localized. It is crucial that insecticides are applied at the right time, which is when the products can reach the exposed larvae before they have a chance to burrow into the stalk.11/10/23, 9:03 AM |

MakeThe Integrated Crop Management article recommends that insecticides should be applied with precise timing to control stalk borer infestations effectively. Specifically, it advises that insecticides must target the larvae before they burrow into the stalk, as once inside, they are protected and the treatment becomes ineffective. For fields with persistent infestations, it is suggested to monitor them annually and apply foliar insecticides to larvae as they migrate from grasses to corn. The article also mentions that insecticides can be tank-mixed with a fast burndown herbicide or applied seven days after a slow burndown herbicide, and border treatments may be considered for localized infestations. It is crucial to scout for larvae inside the whorls to determine the timing of the application. |
