I was reading a post at Town and Country Gardening about drought and grasshoppers (http://survivalfarm.wordpress.com/2012/07/22/home-gardens-drougth-dry-winds-grasshoppers-whats-next/#comment-1513). He lives in Oklahoma and has my sympathy because the Great Plains have traditionally been a challenging place to garden/farm.
Some suggested “climate change” but I am a bit of a history geek, and the Dust Bowl of the 30′s is something most of us actually know very little about, but if you talk to some very old people they will tell you it was pretty bad. Here are some places to start (all links are safe and secure – I went there myself and checked):
- http://geochange.er.usgs.gov/sw/changes/natural/drought/, Climate and Droughts (full NOAA paper)
- http://www.iges.org/c20c/workshops/200201/ext_abs/schubert_ext_abstract.pdf - Long-Term Drought in the United States Great Plains (9 page abstract)

That being said, here are some helpful suggestions I gleaned from Garden’s Alive! (“Getting a Grip on Grasshoppers!”) about natural grasshoppers controls: http://www.gardensalive.com/article.asp?ai=775. Yes, it is a commercial site, but they have “environmentally responsible products that work,” to use their own words. Here are a few suggestions with a few brief quotes from the page:
- Nosema locustae, “a microscopic protozoan parasite of grasshoppers. Often just called ‘Nosema’, it is currently available under a variety of brand names, including ‘Nolo Bait’ and ‘Semaspore.’ It’s a living organism with a relatively short shelf life, so it’s best to buy it just before you use it—which would be in the Spring, when you see the first baby hoppers in their “nymph” stage; a half-inch or smaller. (It doesn’t have much of an effect on adults). Your local county extension agent should be able to identify the right time for your specific region.”
- Fowl: Domestic – Guinea fowl (very effective!) and chickens. Native – attract them (specific suggestions in article).
- Spun polyester row covers. ‘Nuff said.
- Tilling: “Tilling your soil early in the Fall and again in Spring will expose many of those eggs to predators and desiccation.”
- Heavy mulch: Grasshoppers lay next year’s eggs later in summer and heavy mulch (at least 2 inches of old hay, straw, wood chips, shredded leaves, etc.) applied over the winter will prevent many of next year’s young from being able to emerge from the soil (I leave mine on year-round).
- “Molasses is a favorite folk cure that may help right now. Back when I was editor of ORGANIC GARDENING, a Canadian reader reported great success from spraying the perimeter of her garden with a dilute mixture of molasses; apparently, it clogged the pores of hoppers hit by the spray and ones who ate the sprayed plants. Several other readers recommended molasses traps: Mix one part blackstrap molasses with ten parts water, fill wide-mouth jars and buckets a third of the way with this mix and place around the infested area; the hoppers hop in but they can’t hop out.”
- Neem – “Spraying those plants with neem—a natural pesticide made from the seed of a tropical tree—is virtually certain to protect them. In fact, our good buddy Bill Quarles, director of the BIRC—the Bio-Integral Resource Center in Berkeley, California—tells us that neem’s pesticidal properties were first investigated because neem trees were the only plants spared during locust attacks. Bill says that ‘grasshoppers would rather starve to death than eat a plant that’s been sprayed with neem.’ ”
BTW, a little know fact: According to the Bible (Leviticus 11: 20-23), locusts are the only insect that may be eaten: “Every flying insect that uses four legs for walking shall be avoided by you. The only flying insects with four walking legs you may eat are those with knees extending above their feet, [using these longer legs] to hop on the ground. Among these you may only eat members of the red locust family, the yellow locust family, the spotted gray locust family and the white locust family. All other flying insects with four feet [for walking] must be avoided by you.”
Perhaps it was God’s way of giving the people something to eat (in addition to a little culinary vengeance) any time locusts ate their crops.
Anyone ever tried them and have any comments or recipes?
