As a farmer, you must have encountered various pests that harm your crops. Caterpillars can be a significant threat to your soybean crop, and it is essential to control them to maximize your yield. Knowing how to identify and control caterpillars can help protect your soybean crops and ensure a successful harvest. In this article, we will discuss the steps to take in controlling caterpillars in your soybean crop.
Identifying Caterpillars in Soybean Crop
Caterpillars are the larvae stage of moths and butterflies. The most common caterpillars that can damage soybean crops are the green cloverworm, the painted lady butterfly, and the soybean looper.
Green Cloverworm: This caterpillar is highly visible as they are green or yellow-green in color. They have a white stripe running down their side and are around 1 inch long.
Painted Lady Butterfly: The painted lady butterfly is brown with yellow, red, and white spots on its wings. Their caterpillars are usually green and black and can grow up to 2 inches.
Soybean Looper: These caterpillars have a green or brown head and a slimy body that ranges from light green to brown. They usually crawl in a loop-like motion when moving.
Controlling Caterpillars in Soybean Crop
1. Scouting
Scouting is the first step in controlling caterpillars in your soybean crop. Start scouting your soybean crops for caterpillar infestation from mid-June to early August, as this is the period when the infestation usually occurs. Check the upper and lower sides of the leaves to spot the caterpillars.
2. Natural Predators
Natural predators like birds, lacewings, and wasps can help to control caterpillar populations in your soybean crop. Encourage the presence of these predators in your field by minimizing pesticide use and creating habitats for these predators.
3. Handpicking
Handpicking the caterpillars from your soybean crops is a natural and effective way to control their population. Wear gloves and remove the caterpillars from your crops by hand and placing them in a bucket of soapy water.
4. Chemical Control
If the infestation is severe, chemical control may be necessary. Treat your soybean crops with insecticides that specifically target caterpillars. Always read the label carefully, and follow the instructions on the label to avoid harming your crop or the environment.
In conclusion, controlling caterpillars in soybean crop requires regular scouting, encouraging natural predators, handpicking, and using chemical control when necessary. Always adopt the most sustainable option to ensure long-term crop protection. With these tips, you can effectively control caterpillars and protect your soybean crop.
