What are the diseases in the garden doing?
Parasitic diseases and nonparasitic disorders can cause serious vegetable losses in home gardens. Many species of microorganisms — including fungi, bacteria, viruses, phytoplasmas and nematodes — cause diseases of vegetable crops. For disease to occur, plant pathogens must come in contact with a susceptible host plant. On the other hand, pathogenic fungi cause plant diseases such as anthracnose, leaf spot, rust, wilt, blight, coils, scab, gall, canker, damping-off, root rot, mildew, and dieback. Systemic foliar pathogens are major causes for yield and commercial crop losses and diminished crop quality [2].
What are the agricultural pests?
Agriculture is the practice of cultivating plants to produce food, fiber, medicinal substances, and other essential products for human life and the economy. Throughout history, various agricultural techniques have developed and adapted to the climate, topography, and culture of each region. Four Types of Agriculture: Pastoralism, Shifting Cultivation, Subsistence Farming, Intensive Farming – Testbook.
What are the three great pests?
Three of those “pests” made relative sense: Flies, mosquitoes and rats can carry disease, and humans still try to control them today. But why were sparrows lumped in with the other three? Mao, it turns out, wanted to prevent the abundant birds from eating grain seeds — a perceived threat to farm production. In 1958, China included the sparrow in its “Four Pests Campaign,” which aimed to improve agricultural activity and human health by eradicating flies, mosquitoes, rats and sparrows.
What are pests and diseases?
A pest can be a plant (weed), vertebrate (bird, rodent, or other mammal), invertebrate (insect, tick, mite, or snail), nematode, pathogen (bacteria, virus, or fungus) that causes disease, or other unwanted organism. A disease on the other hand is any disorder that interferes with the normal functions of plants. A pest is classed as an animal which could be harmful to humans. They may for example damage crops, livestock or forestry, cause a nuisance by invading homes and work spaces or cause illness by spreading disease. There are four different types of pests – rodents, insects, birds and wildlife.Examples of significant public health problems caused by pests include: Vector-Borne Diseases – Infectious diseases such as Zika virus, Lyme disease, and rabies can be carried and spread by vectors. Disease vectors include mosquitoes, ticks, and rodents and other animals.
What is the most common type of pest?
