Save Flowers and crops From the destruction of pesticides

Pest Nature Resources. They help us to balance our surroundings. There are two types of insects that are beneficial and bad for humans.

Beneficial pest helps in pollination or for food, clothing and settlement for the people. Bees make honey; The silk worm creates a pearl of silk yarn, and the coral worm dies and rises through the coral reefs in the sea.

Again, the damaged insects bring calamity to flower-fruits, vegetables, and crop fields. They may annihilate the decorated gardens of nature and the field of crops grown in human labor. The attack of locusts can destroy a country's crop and cause famine. The mosquito-flies, the barks, these insects carry various pathogens.

People from the middle of the eighteenth century became aware of the harmful insects. As a result, they started looking for different ways to prevent pest. The first stars are used for this purpose, various natural elements including livestock urine or tobacco.

But 'insecticide' today only refers to chemical pesticides. After spreading 'pesticides' it tends to be on the trees and leaves. Some insects eat straws and leaves of trees. Then the fine particles of insecticide enter the insect body and cause them to die. The pests that do not eat the tree or leaves of the plant, but come in contact with insecticides in the lymphocytes; As a result, insects die. Because chemical pesticides work long time, trees or crops can be preserved in the face of insect attack.

After World War II, there was a revolution in the formation and use of pesticides. In fact, two chemical pesticides, DDT and BHC, have created a surprise around the world.

These two insecticides give incredible results to prevent harmful pest. And it protects the fields of abundant crops, flowers and fruit gardens. Humans survive from mosquito-fishes. It is resistant to the spread of various diseases. Within a few days, DDT and BHC have become a serious threat to animal production.

The insect pests not only killed the insect pests, but also killed countless pesticides. Birds have died due to insecticide poisoning. Paddy, jute and wheat fields scattered in the fields, rain, irrigation and banana water in the ponds and water bodies, so the fish have died. And people are suffering from these complex and difficult diseases.

It is also seen that DDT is not lost in nature in any way, their toxicity has survived over the ages. In view of this, the United States banned the use of DD in 1973. Later, except for India, all the countries of the world banned DDT.

All types of pastestasy or pesticides are mainly used for the poisoning of crops, to curb the harmful insects, germs, weed and rats. Different types of pastestasy include insecticides or insecticides, phanedosides or antidotes, vidyaside / herbicide, methicides for spiders, and rodenticide for rats.

The first experimental pesticide was used in Bangladesh in 1951. In 1956, the government imported two tonnes of insecticides for Bangladesh land. The government of Bangladesh gave 100 percent subsidy to insecticide till 1974. Later, in 1979, the subsidy was completely withdrawn and since 1980, private sector pesticides have been allowed to be imported.

In the beginning, a slogan by the government to popularize insecticides among the peasants was - 'Fools eat insects'. The use of pesticides has become popular in a short time in the propagation of public authorities.

In recent times, the biodiversity of agricultural land in Bangladesh - which is one of the worst, is horrifying. In the agricultural land, especially rice fields, snail-mussels and various types of small fish were once seen. Now they are missing a lot.

Nature Tiller is said that the worm also is no longer available in agricultural land. Fisheries and birds have lost their livelihood to eat insects on crop fields. In the field of crop, honey bees and buffalo rumors are also collected from flower to honey, due to various toxicity. Many other reptiles present in the agricultural environment are extinct today.

In recent years, the use of weedicides in crop fields is threatening various plant species as a threat. According to experts, due to the use of weedicides, new species of weeds will arise in the future, which can not be suppressed in any way.

Some of the insecticides used in the country are extremely high toxic which are extremely harmful to humans and the environment. Pesticides in this category are known as 'Darti dozen', 'Popes' or 'Nasty Nine'. Although these pesticides are prohibited due to residual effects in different industrialized countries, many of them exist in Bangladesh.

Also prohibited in the world, including red-listed highly toxic insecticides. In our country, multinational companies are importing and marketing these very harmful pesticides in the hope of more profit.

Two types of insect pests and diseases are going to die of insecticide. Snakes, frogs and fish To save the environment, these animals must be kept alive. They are dependent on one another in the food chain of living organisms. Once upon a time, using the traditional folk knowledge, the balance of the neighboring ecosystem could have been run properly.

The hope is that integrated pest control system has been introduced in agricultural work by the initiative of Agriculture Extension Department and many NGOs. This will reduce the cost of farmers and the environment will be good. These people are in the knowledge - if they put kanchi and stalks in the fields, birds can eat insect pesticides in the fields. Sprinkle insects by torching a torch. To protect environment and human health, there will be a spread of anti-pest suppression movement in the country.
