This would all depend on the type of pesticide that you are using and what it is labeled for; Acaricide kills mites, Algicide kills algae, Avicide kills birds, Bactericide kills bacteria, Fungicide kills fungi,Herbicides kills weeds, Insecticides kills insects, Lapricide kills lamprey, Miticide likks mites, Molluscicide kills snails and slugs, Nematicide kills nematodoes, Piscicide kills fish, Rodenticides kills rats and mice.
Different products work in different ways and some in multiple. the most common ones act on the nervous system, but some are dessicant and simply dry out the exoskeleton, cause internal bleeding (rat poisons) or are common stomach poisons like baits or dusts injested when they groom.
No but it can badly burn some plants if wrong product used
Yes, in high enough doses or if something/someone is exposed to pesticides for a long enough time.
Rachel Carson used the term "biocide" to describe the effects of new generation pesticides on the environment. She highlighted how these chemicals not only killed the targeted pests but also had harmful effects on non-targeted organisms, leading to detrimental ecological consequences.
Pesticides are of various chemical nature which on being applied to plants nuture them by warding of pests. Pesticides, when applied to plants, on excess irrigation, they percolate down the soil thus polluting the depleting reservoire of groundwater. Pesticides are composed of various chemicals like cadmium, mercury which enter the human body via the food chain which has its dependence on groundwater. Chemicals like cadmium cause death on consumption. Pesticides not only harm the insects and pests but also the local fauna like snakes and earthworms which are natural pesticides and decomposers. Snakes kill the rats living in the farm.
The insects themselves, since a restaurant can be shut down even if they are not alive.
The first steps to protecting any crop from the pests which can damage or kill it should always include cultural controls. These are agronomic methods which can help reduce or control various kinds of pest species. Pesticides should always be the last resort when all other methods prove insufficient for economic control. US cotton farmers have found that cultural controls are rarely enough to prevent serious damage to the crop, so they are left with little choice but to use the pesticides. The only alternative is extremely expensive and frequently unavailable hand labor, which doesn't work on all kinds of pests.
They are designed to be, but only for the targeted pest. They are safe to use provided used responsibly. Pesticide poisoning is possible, but the people at greatest risk are those with repeat exposure (that work with it routinely)
Pesticides are poisons: they kill the particular pest that they are intended to kill, but then they seep into the soil or into water systems, where they can kill other needed insects, can be ingested by fish or other aquatic life, and from there be ingested by birds or larger animals. A buildup of residual pesticides in a given area can do tremendous damage to the entire ecosystem.
Selective weedkillers will only kill the targeted weeds. Total weedkillers will kill all green plants. Therefore if the weedkiller does not kill grass but other weeds in the grass, it is a selective weedkiller.
You should not kill all insects...only those harmful insects...some insects benefit for us..some they harm us especially pests...so,don't kill ALL of them
The only way to kill a colony of farrow ants is to kill their queen. You can try pesticides that you can purchase at any store but you need to apply it directly to the nest or ant hill.
The only difference - is that the organic cotton has been grown without the use of artificial pesticides etc. Farmers have used natural products (eg natural fertilizers) to aid growth, and using other insects to keep pests under control rather than use manufactured pesticides.
the one and only solution against chemical pesticides
Bio-pesticides are pesticides that only contain natural materials rather than chemicals found in most other forms. Essentially they are environmently-friendly pesticides.
