This is Jason Lamb with your Gardening Minute.
Grasshoppers are a yearly problem in New Mexico. Especially if there is enough food and forage for larger populations to exist. Last year grasshopper populations in Quay County were high and we can assume that populations this year will also be high unless something like a long dry spell occurs that will reduce populations.
Since grasshoppers are capable of migrating from location to location, they are especially problematic. They begin in open rangeland where the eggs were laid. Then they feed on grasses and weeds, when these are gone, they can migrate to other locations and feed on more plants.
Insecticides can be used to kill grasshoppers and are more effective when grasshoppers are small but when used on a limited areas such as small private property, the effects are minimal. All areas need to be treated in a comprehensive multi agency program to have a greater impact but even then it must be economical to warrant control.
Insecticides that have a long residual are more effective against grasshoppers and can be applied around the boarders of properties for crawling insects and can reduce local populations. But also pose a high risk to beneficial insects. If you choose to use insecticides, be sure to choose a product labeled for your plant types and grasshopper control and always, follow the label directions of the product.
If you would like more information on grasshopper control please contact the Extension office at 461-0562. This has been your Gardening Minute with Jason Lamb your Quay County Ag. Extension Agent. Where are programs are open to everyone.
