While gardening is as old as farming, it is growing rapidly. The bug control market has grown more than 50% in the last five years, making it a $7 billion industry. As more people move into urban areas and rural regions, pest control is becoming an even more urgent issue. The benefits of bug control are widespread, but a better understanding of what causes them and how to solve them will help you understand your options better.
Plant-parasitic nematode infestations can damage crops in many ways. The most common nematode attack is the northern root-knot nematode, which overwinters as an egg in the soil. In the spring, second-stage juveniles hatch from the eggs and migrate to the roots of host plants. The nematode establishes feeding sites in the pro-vascular tissue behind the root cap of the plant, causing damage to the plant’s root tissues. It then partially digests the contents of the host cell before feeding, which is why plant damage is often a direct result of the feeding process.
If you suspect a new infestation of plant-parasitic nematops, it is important to study the field’s history. If there have been nematode problems in previous years, they are likely to continue in your current field. If yields have been reducing steadily, you may have an ongoing problem. A new field infested with nematodes often starts as a small spot and slowly intensifies over time. Erosion, harvesting, and other factors can contribute to the spread of nematodes throughout the area.
Convergent lady beetles
Pesticides are not the only method of controlling insects. Many other pest control Adelaide methods have failed to control some common pests. For example, harrowing a field leaves an area that is highly susceptible to insect infestation. The harrowing process scatters eggs and larvae all over a field. Hence, the animals cannot graze in this area. However, it is possible to harrow a field and release divergent lady beetles, although this method is not as effective as it sounds.
Pesticides have several advantages. First, they are effective in controlling some pests without harming their natural enemies. Second, they are effective for longer periods of time and can reduce the damage done to plants. But they should only be applied to heavily infested areas of a field. In addition, they should target a specific invertebrate, such as caterpillars. Other pesticides have little persistence, such as contact insecticides. Examples of contact insecticides are azadirachtin, insecticidal soap, neem oil, and pyrethrins. These are generally mixed with piperonyl butoxide for maximum effectiveness.
Biological control methods
Biological control is a natural process in agriculture that is often applied in agriculture. The method uses beneficial organisms, such as insects, to control pests. These organisms may be native to a region, but can also be introduced to a new area. In this way, a natural enemy may establish itself on a specific crop, with the hope that this enemy will become permanently established. Biological control techniques include drench and inundative release.
Some of the most commonly used biological control agents are parasitoids. These insects are small, wingless creatures that feed on aphids, mealybugs, whiteflies, scales, and insect eggs. Their larvae feed on the eggs of aphids and other pests, and they often have a variety of predatory behavior. The most common lady beetle for horticulture is the Convergent Lady Beetle, which is collected from overwintering colonies. The convergent lady beetle has better dispersal abilities. Parasitic flies can also be purchased commercially.
