You can name any crop which is grown by humans for use by humans. Corn, soybeans, wheat, cotton, peanuts, tomatoes, lettuce, onions, potatoes, and apples come to mind easily.
"Pests" are anything which can damage the quality or yield of the crop being produced, so it includes weeds, insects, nematodes, fungi, bacteria, rodents, and birds.
As often as the crops need it. Any good farmer will not spray a crop until it needs it for some reason, mainly due to the expense. Some crops such as wheat may need only one or two sprays during the entire growing season. Fruit crops, however, may need sprayed with something or another once or twice a week.
Planting the same crops on the same soil for many years is called monocropping. This practice can deplete the soil of essential nutrients, increase susceptibility to pests and diseases, and reduce overall crop yields over time. Rotation of crops can help prevent these negative effects.
Planting the same crops on the same soil for many years can lead to a depletion of nutrients in the soil, which can impact plant growth and yield. It can also increase the risk of pests and diseases that thrive on a specific crop. Crop rotation is a farming practice that can help replenish soil nutrients and break pest cycles.
There is no exact number, as it can vary depending on the type of crop and location. However, on average, crops are sprayed with multiple pesticides to protect against pests, diseases, and weeds throughout the growing season. Organic crops are not sprayed with synthetic pesticides, but may still use organic-approved pesticides.
cotton bollworm, pink bollworm, thrips, cotton square borer, cotton aphids, whiteflies, fleahoppers, boll weevils, and many other occasional pests
Planting the same crops on the same soil for many years can lead to soil depletion, where essential nutrients for plant growth are used up. This can result in decreased crop yields, increased susceptibility to pests and diseases, and soil erosion. To prevent this, crop rotation and use of cover crops are important practices to maintain soil health.
Snakes can be pests as the venomous species are a danger to people who come too close or accidentally step on them. Large snakes sometimes prey on chickens, rabbits, and similar sized animals raised by farmers. However snakes can also be beneficial. Many snakes eat mice and rats that could otherwise damage crops.
In theory birds are responsible in many food chains for the distribuation of seed, eating some of the pests that prey on the crops we require to live. So they are a very important part of the food chain
Grass, and other plants `Back in the day when there were many farmers and Wild Horses (escapees or bred that way) running around, they would eat the farmers crops. This explains why they used to be considered "pests" `
Rats are not considered endangered species. In fact, many rat species are considered pests due to their abilities to spread disease and eat crops. Some rat species thrive in human-influenced environments.
Many different animals eat wheat plants, including insects such as aphids and cutworms, as well as larger animals like birds and rodents. In agricultural settings, wheat plants are also susceptible to damage from pests like rabbits and deer. Farmers may use various methods to control these pests and protect their wheat crops.
Many kinds of insect pests destroy forests by eating the shoots and spreading diseases.
