What are some biological alternatives to chemical pesticides?
Some biological alternatives to the use of chemical pesticides is to use biological control agents like fungi, bacteria, or viruses.
What reason might a farmer have for using biological control instead of chemical pesticides?

What is the difference between biological control and pesticides?
Pesticides.Pests that affect human health and crops are a major problem.However, one possible consequence of using pesticides is that beneficialorganisms living in the same environment as the pests could also beharmed. This can happen because many pesticides kill more than justthe pest. For example, the lygus bug are pest that feedson alfalfa and canola plants and causes severe damage to these crops.However, pesticides that are sprayed to kill lygus bugs also kill bees.Another downside to using pesticides is that they can also harm thebeneficial insects that normally prey on the pests. This can result inthe populations of pests actually increasing because there are fewerorganisms to prey on them!Biological control.Another way to control insect pests is to use their natural enemies.This method, called biological control, can be very effective and limitsor eliminates the need for pesticides. For example, leafy spurge is aweed that was accidentally introduced into Canada in the late 1800s . Leafy spurge grows faster than naturally occurringpasture grasses. Cattle will not eat leafy spurge, so land that is infestedwith this weed cannot carry livestock. The black dot spurge beetle is asmall beetle that feeds on leafy spurge. The beetle was introduced into Alberta in 1983, and has been very successful incontrolling the spread of leafy spurge. Desirable plants, such as pastureand rangeland grasses, are returning to the areas where leafy spurgeused to grow. Although biological control can work very well, there can be risks.Whenever a new organism that is not native to the area is introducedto an ecosystem, there is always a risk that it will cause harm.
How is biological control used to control pests?
Biological control consists of using predator pests to control the target species. It is becoming quite a common practice in commercial orchard and farming operations. A predator insect is introduced to the crop and it then consumes the pest that is causing grief. Mites are one in particular that are very difficult to remove with traditional pesticides but predator mites usually give great results. They can be bought at commercial farm suppliers or some of the larger garden centers. Be Happy, Barry
What are biological control of pests?
Biological control is the beneficial action of predators, parasites, pathogens, and competitors in controlling pests and their damage.

What types of pesticides are used for wheat?
Herbicides to control weeds, sometimes fungicides to control certain kinds of infections, and rarely insecticides to control harmful insects.

Which kinds of pesticides are on the market right now?
Transport, pro control, Gentrol, Advion, Delta dust are some pesticides. Pesticides used in agriculture include Round-up (glyphosate) and other herbicides, insecticides, fungicides, etc. Insecticides are used to control household pests.
Type of farming that doesn't use pesticides?
* Organic agriculture actually organic farming does use pesticides, what you're looking for is "biological control" which means it allows the use of synthetic fertilizers but trades chemical pest control with biological pest control. in biological control one applies parasitic wasps, entomophagic fungie and other such agents in much the same way one would apply chemical pesticides.
What is biological control used for?
Biological control is the use of a pey species to control pests and parasites i.e. to use Encarsia formosa the Chalcid wasp to control Whitefly. This avoids the use of pesticides.
What are fertilizers and pesticides?
Fertilizers are materials designed to feed (provide) nutrients to plants. They come in liquid and dry forms, fast and slow release, inorganic and organic, and so on. Pesticides are materials designed to eliminate, prevent or control pests, such as: insects, slugs, snails, diseases like fungus (mildew, rots, smuts), and so forth. Herbicides are materials designed to eliminate, prevent or control unwanted plants (what we normally call "weeds").
What has the author Edward C Monnig written?
Edward C. Monnig has written: 'Human health risk assessment of herbicide applications to control noxious weeds and poisonous plants in the Northern Region' -- subject(s): Control, Herbicides, Weeds, Toxicology, Plants, Effect of herbicides on, Health risk assessment 'A summary of the status of biological control of major noxious weed species in Idaho, Montana, and North Dakota' -- subject(s): Noxious weeds, Biological control
What is the definition of pesticides?
A pesticide is a chemical substance sprayed on crops to kill insects, pests and bacteria. The chemical agents called pesticides include herbicides (for weed control), insecticides, and fungicides. More than half the pesticides used in the United States are herbicides that control weeds. The United States Department of Agriculture (USDA) estimates indicate that 86 percent of U.S. agricultural land areas are treated with herbicides, 18 percent with insecticides, and 3 percent with fungicides. The amount of pesticide used on different crops also varies. For example, in the United States, about 67 percent of the insecticides used in agriculture are applied to two crops, cotton and corn; about 70 percent of the herbicides are applied to corn and soybeans, and most of the fungicides are applied to fruit and vegetable crops.They kill "pests".
What are solutions to biological magnification pesticides?
There are several solutions to addressing biological magnification of pesticides. One approach is to encourage organic farming practices, which avoid the use of synthetic pesticides altogether. Additionally, implementing integrated pest management strategies can help reduce reliance on chemical pesticides by utilizing alternative methods such as crop rotation, natural predators, and mechanical pest control. Finally, strict regulation and monitoring of pesticide use can help prevent excessive accumulation of toxic compounds in the environment.
What is the effect of using herbicides and pesticides?
Pesticides are designed to kill of as many insects as possible; they´re poison in the truest sense of the word. Other animals may die too if they eat from it, or the insects that have or are about to die of it. And as pesticides are sprayed over our crops, we too may ingest them if we don´t wash our food thouroughly, and even then it might be too much to wash off. Luckily chemical pesticides are being replaced by biological control such as natural enemies to ward off pests.
What is biological weed control?
Historically, you sent someone out into your garden or field with a hoe, and they chopped weeds or pulled them out by the roots. Chemical weeding involves spraying herbicides that target the most common weeds--not including the crop. Today, you might release an insect that feeds on the weeds but leaves the crop alone. These biological methods are not in common use yet. The biological method to get rid of tomato worms (horn worms), for example, is to pluck them off and stomp on them. Of course, that is pest control, not weeding.
