The third generation of pesticides are made of chemicals that break down in the environment quickly, as compared to the second and first generation which were DDT and arsenate of lead respectively.
The "first generation" pesticides were largely highly toxic compounds, such as arsenic and hydrogen cyanide. Their use was largely abandoned because they were either too ineffective or too toxic. The "second generation" pesticides largely included synthetic organic compounds. ('Synthetic' here means made by humans -- not naturally occurring, while 'organic' means carbon containing, not to be confused with the popular use of "organic" as in "organic farming".)
Widely after the second world war.
in second generation of computer transistor were used transistor are used instead of vaccum tube are used in first generation high level langauges such as gobsl, fortran are used
no, second generation. third generation computers used ICs.
Second generation computers used electronic transistors. A small number used magnetic amplifiers.
The Second Generation Computer used transistors
First & second generation is usually in reference to anticoagulants (rodenticide) & when product was developed. First gen is about the 40's to 60's. I have not heard the term in reference to pesticides.

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.
The first minicomputers were second generation computers, but the most well known minicomputers were third generation computers.
