Pesticides Uses

Insect have more species (over one million already described) than any other form of animal life and are in many ways the most indestructible form. About 1 percent of the species offer hazard to human and animals. Human and pests fight a continuous battle for food and shelter. Insects alone claim about 10 % of our crops in US, and about 14 percent in worldwide, various misery causing diseases are carried by insect malaria, yellow fever, typhus, and plague to name a few. For us to survive at current population levels, pesticides must be used and new ones constantly developed. When insecticide applied widely, all but a few of the local insects are destroyed, but the remaining ones are those most resistant to the destroying agent. After destroying generation, this selection makes the surviving insects increasingly resistant to the destroying agent. Eventually, complete resistance may occur. This phenomenon is seen with medical product, and all types of pesticides. In an effort to retard the rate at which such resistance develops, the concept of integrated pest management has been developed, which will be more fully discussed later.

The annual loss attributed to agricultural pest nears 10 percent of the total agricultural production value per year, perhaps $15 billion in the united states alone. Without chemical control and accompanying means such as IPM, the losses would be impossibly large and the quality of products unacceptably low. Every citizen must be concerned with this tremendous loss and take part in the warfare against normal and constant enemies. Without pesticide use, we starve. Use of pesticides is a most important step in the conservation of our resources and in increasing the productivity of our soil. The low cost manufacture of increasingly complex chemical agent offers an exception challenge to processing specialists.

Chemistry pervades every of agribusiness. The use of chemicals was limited to about 50 compounds in 1940, now several hundred are used in perhaps 50,000 commercial formulations. Effectiveness and economical production are important, but safety to farmers, consumers, and the general public is so important that federal laws strictly demand it.

Sodium Sulfite and Sodium Hydrosulfite

Sodium Sulfite Sodium sulfite is a compound that is very easily oxidized. For this reason, it is employed in many cases where a gentle reducing agent is desired, e.g. to bleach wool and silk, as an antichlor after the bleaching of yarns, textile and paper, as a preservative for foodstuffs, and to prevent raw sugar solution from colouring upon evaporation. It is very widely used in the preparation of photographic developer to prevent from oxidation from hydroquinone and other agents. It has a small application in the field of medicine as an antiseptic and as an antizymotic for internal use. About 60% of the total merchant market is in the paper Industries. While merchant capacity is about 145,000 t/year, the paper mills have twice capacity to captive use. The demand for boiler feed water treatment is about 15%. It is use to remove oxygen from water and thus help to prevent corrosion and scale formation. These were four major production in 1891, one of which provided 50% percent of the...

Viscose Fiber Production Process

Viscose fiber is a base material for textile industry. The first production of this kind product is in Indian than spread over the Europe and United States also in South Asia Country like in Indonesia. Viscose fiber is produced to anticipate the shortage of natural yarn for raw material to produce yarn in textile industries, beside synthetic yarn as replace natural cotton to produce fabric. This one is a simple drawing of viscose fiber production process . Viscose fiber is used to substitute the using of cotton as raw material for textile industry. Beside of cotton availability will not enough to supply market demand in the future, also cotton just available on harvesting season. If people just depend on cotton to produce textile then people will shortage of raw material to produce textile. Using viscose fiber to fulfill of textile industry will not any shortage raw material, beside the price is lower than cotton, viscose fiber also have better quality compare with synthetic fiber fo...

Sulfur

Sulfur or sulphur is a naturally occurring, yellow, water insoluble solid element. Its chemical symbol is S , its atomic number is 16 and its atomic weight is 32.064 sulfur is nonmetal and a member of the oxygen family of elements, which constitutes Group VIA of the periodic table. The discovery of sulfur predates recorded history, and the element has been used since ancient times. The early medical books of Dioscorides of Greece and Pliny the Elder mention sulfur, and fumes from burning sulfur were used in religious ceremonies and for fumigation. Alchemists recognized sulfur as a mineral substance that can be melted and burned. It was first classified as an element by Antonie Lavoisier in 1777. Sulfur Occurrence On earth, sulfur is widely distributed in its elemental state as a secondary mineral or as a volcanic deposit, as well as in combination with a number of metals. Large sedimentary deposits of the almost pure element, mainly of Tertiary age, are found in the coastal r...
