What Pesticides can Do to Farmers's Crops

Pesticides are chemicals that kill pests. Farmers often use pesticides on crops to kill unwanted pests, including insects and rodents, to prevent them from destroying crops. Farmers choose chemical pesticides to protect their crops because it is economical. The benefits from using pesticides, in terms of crop yield, outweigh the costs of using pesticides.

When the first synthetic chemical Pesticides was developed the pesticide in 1939. It was DDT. It proved effective against the Colorado potato beetle, an insect that was destroying crops across the United States and Europe. Then many farmers use synthetic chemical pesticides, organic farmers sometimes use naturally occurring chemical pesticides on crops to control pests.

Farmers always use chemical pesticides to protect their crops. Insects such as beetles and worms can easily infest and destroy crops. Rodents also cause damage to crops both while they are growing and in storage. But using pesticides allows farmers to kill the pests without destroying their crops. Using pesticides can help a farmer profitably produce a crop in an area where he otherwise could not or to extend a growing season.

Pesticide use can help to extend the shelf life of a food or maintain product quality. In some cases, pesticides can protect human health. That is the case with organisms on plants that can cause toxins in the plants. Among those potential toxins is ergot, a fungus that infects some grains and produces a toxin. When eaten in sufficient quantities the toxins cause ergot poisoning.

Farmers use pesticides because they act fast, quickly knocking out pests before the pests can destroy much of the crop. In addition, many pesticides are broad spectrum so they protect crops against more than one pest, which saves time and money. Using pesticides is also less labor intensive than the biological controls used by organic farmers such as crop rotation, companion planting, hedge rows between fields and not planting large amounts of unbroken acreage in any one crop or plant species.

But pesticides can help to protect crops and it may remain in the plants when farmers sell them to people, these pesticides is not easy to remove if farmers used it too much during the growth of crops. So it is quite important to choose the vegetables and fruits without pesticides or too much pesticides on them. Too much pesticides on food can lead to a bad healthy to our body. If you are not sure to tell which kinds of food are safe to eat, you can use Greentest nitrate detector to test it, it will shows you the pesticides(nitrate) level in quickly time and shows you it is under the safe control or not.

How is nitrate produce

Fresh vegetables stored for a long time, rotten vegetables and placed over a long time of cooked vegetables, the original dish of nitrate in nitrate reducing bacteria under the action can be converted to nitrite.

The vegetables nitrate containing high is a global problem, all over the world appeared nitrate in vegetables containing high amounts of situation. Nitrate itself is not toxic. Prolonged storage of fresh vegetables, rotten vegetables and put long cooked vegetables, the original vegetable nitrate in nitrate reducing bacteria can be transformed into nitrite.

Saliva and stomach bacteria can also be the reduction of nitrate to nitrite. Nitrite may influence hemoglobin oxygen delivery ability. Most people due to consumption of nitrate and nitrite containing higher amounts of vegetables and suffering from "blue baby syndrome" opportunity is extremely small, in very few circumstances baby to eat the high nitrite content of vegetables, can cause "blue baby syndrome".

Nitrite to the adult lethal dose, different studies showed the results do not. Studies suggest that human intake of 0.2 ~ 0.5 grams can cause poisoning, 3 grams can be lethal.

Use nitrate tester to check your vegetable and fruits nitrate level, whether they are in a healthy amonut.

 Why Need Greentest Nitrate Tester

Fertilizers that contain necessary elements for plant growth are used for cultivating fruits and vegetables. However, misuse of production technology, usage of prohibited fertilizers, pesticides and chemicals, as well as an increased level of fertilizer concentrations in the soil can all result in a serious damage to your health. Of all the substances that are transferred to the soil from fertilizers, nitrates are one of the most harmful if consumed in excess. Continuous intake of food with a high nitrate content may lead to an elevated risk of serious diseases, which is also a representative foodsafety problem.

Are you being exposed to dangerous agricultural chemicals? Many farmers apply too much fertilizer. This can result in unsafe levels of fruit nitrate and vegetable nitrate content. It’s especially dangerous to children as their inadequacy of food safety and sanitation awareness.

Nitrates and nitrites in fruit and vegetables: The risk to human health

Most health conscious people know about the dangers of pesticides in fresh fruit and vegetables. Few are aware that fresh fruit and vegetables expose them to dangerous nitrates.
