There are many different types of pesticides, each is meant to be effective against specific pests. The term " -cide " comes from the Latin word " to kill. Antimicrobials control germs and microbes such as bacteria and viruses. Biopesticides are made of living things, come from living things, or they are found in nature.

Impact of pesticides use in agriculture: their benefits and hazards

The term pesticide covers a wide range of compounds including insecticides, fungicides, herbicides, rodenticides, molluscicides, nematicides, plant growth regulators and others. Among these, organochlorine OC insecticides, used successfully in controlling a number of diseases, such as malaria and typhus, were banned or restricted after the s in most of the technologically advanced countries. The introduction of other synthetic insecticides — organophosphate OP insecticides in the s, carbamates in s and pyrethroids in s and the introduction of herbicides and fungicides in the s—s contributed greatly to pest control and agricultural output. Ideally a pesticide must be lethal to the targeted pests, but not to non-target species, including man. Unfortunately, this is not the case, so the controversy of use and abuse of pesticides has surfaced. The production of pesticides started in India in with the establishment of a plant for the production of BHC near Calcutta, and India is now the second largest manufacturer of pesticides in Asia after China and ranks twelfth globally Mathur, There has been a steady growth in the production of technical grade pesticides in India, from 5, metric tons in to , metric tons in

Insecticides are substances used to kill insects. Insecticides are used in agriculture , medicine , industry and by consumers. Insecticides are claimed to be a major factor behind the increase in the 20th-century's agricultural productivity. Insecticides can be classified into two major groups: systemic insecticides, which have residual or long term activity; and contact insecticides, which have no residual activity. The mode of action describes how the pesticide kills or inactivates a pest.

Acknowledgement 2. Acknowledgement I wish to express my deep gratitude and sincere thanks to the Principal, Sheetal Mann, Modern Convent School for her encouragement and for all the facilities that she provided for this project work. I extend my hearty thanks to Teena Singh, Chemistry teacher who guided me to the successful completion of this project. I take this opportunity to express my deep sense of gratitude for her invaluable guidance, constant encouragement, immense motivation which has sustained my efforts at all the stages of my project work. I cant forget to offer my sincere thanks to parents and also my classmates who helped me to carry out this project work successful and for their valuable advice and support which I received from them time to time.

Fertilizers & Pesticides

This project is a bonafide piece of work carried out with the consultation of supervisor. Pal and Mrs. Bala for their guidance and advices to complete my work successfully. I also thank our principal for providing me all the facilities to finish the project on time. I also take this opportunity to thank my Parents for the countless blessings showered on me while doing the work and for encouragement and support in my humble venture. In the past decade there has been a tremendous increase in the yields of various crops to meet the demand of overgrowing population, achieved by using pesticides and insecticides.

Introduction

Ничего не трогайте. Ничего не читайте. - Энсей Танкадо… родился в январе… - Пожалуйста, - вежливо сказал Беккер.  - Положите на место. Офицер еще какое-то время разглядывал паспорт, потом положил его поверх вороха одежды. - У этого парня была виза третьего класса. По ней он мог жить здесь многие годы.

Хорошая новость. Звонок из Соединенных Штатов. Он улыбнулся. Значит, все правда. - Из какого именно места в Штатах? - спросил .

 Решайте! - крикнул Хейл и потащил Сьюзан к лестнице. Стратмор его не слушал. Если спасение Сьюзан равнозначно крушению его планов, то так тому и быть: потерять ее значило потерять все, а такую цену он отказывался платить. Хейл заломил руку Сьюзан за спину, и голова ее наклонилась. - Даю вам последний шанс, приятель.

Но если я вызову агентов безопасности, весь мой план рухнет, - подумал .

 Конечно, согласился. Вы же мой шеф. Вы заместитель директора АНБ. Он не мог отказаться.

Insecticide

Ничего страшного - это глупая болтовня. То, что там происходит, серьезно, очень серьезно.

 Нам нужен этот предмет, - сказал Фонтейн.  - Где сейчас находится Халохот. Смит бросил взгляд через плечо.

Он использовал подход, который никому из нас не приходил в голову. - А зачем это нам? - спросила Сьюзан.  - В этом нет никакого смысла.

Мысли ее вернулись к Дэвиду. Сьюзен надеялась, что с ним все в порядке. Ей трудно было поверить, что он в Испании. Чем скорее будет найден ключ и все закончится, тем лучше для. Сьюзан потеряла счет времени, потраченного на ожидание Следопыта.
