Challenge your understanding of soil pest management in agriculture with questions on identification, control strategies, and their impacts. Deepen your knowledge of sustainable practices for healthy crops.
Which of the following pests is commonly known to attack plant roots in agricultural soils, often causing stunted growth in crops such as corn and potatoes?
Explanation: Wireworms are larvae of click beetles that attack roots and underground stems, causing stunted or wilted plants. Aphids and spider mites feed on above-ground plant parts, while leafhoppers typically damage leaves. Only wireworms directly affect roots as described.
What is one advantage of using beneficial nematodes for controlling soil-dwelling insect pests in vegetable fields?
Explanation: Beneficial nematodes are microscopic organisms that control certain soil pests without damaging plants or soil health. They do not need chemical support, do not attract pests, and do not reduce soil fertility, making them an environmentally friendly option.
Which cultural practice can help reduce populations of soil pests like cutworms in a field?
Explanation: Crop rotation interrupts pest life cycles by changing host availability, lowering infestations. Increased irrigation and excessive fertilizer may worsen pest problems, while leaf pruning targets above-ground issues rather than soil pests.
When using soil-applied insecticides to manage pests, what is an important consideration to minimize negative impacts?
Explanation: Using soil-applied insecticides according to label guidelines ensures safe and effective pest control, minimizing environment and health risks. Indiscriminate or excessive use can harm non-target organisms and humans, and ignoring safety gear is dangerous.
How can maintaining healthy soil organic matter help in managing soil pests in crop production?
Explanation: Healthy soil organic matter fosters beneficial microbes and organisms that compete with or reduce pest populations. It does not completely eliminate pests, nor does it attract more. Nutrient leaching is not a direct effect of maintaining organic matter.
