Protecting Crops with Climate Changing

Abstract

The use pesticides to protect crops from damage caused by insect
pests, fungi and weeds, really began back around 1890, when some
farmers splashed some copper sulphate to stop people pinching
their grapes in France, that was soon followed when Professor
Millardet at Bordeaux University noticed that the Copper sulphate
had reduced the fungus on the vines. He introduced his Bordeaux
mixture which was sprayed using the first knapsack sprayers [1].
At the same time in the USA, knapsack sprayers were introduced
to treat potatoes with Paris green to control the Colorado beetle
that had spread from Mexico.
