Pesticide application system eliminates manual pumping operations and reduces handling of pesticide concentrates

In a pesticide application system having a cylinder in which a pesticide solution is placed and in which a pressure head is created by manual operation of a hand pump, said cylinder requiring replenishment with pesticide solution several times during the course of the workday, said pressure head having to be recreated each time said solution is replenished, said pesticide solution comprising a mixture of pesticide concentrate and water manually mixed by a pesticide application system operator each time said cylinder is replenished, the improvement comprising:

• a pesticide replenishment tank in which is placed a selected amount of solution selected for several working day's operations and in which a pressure head is created, said pressure head being greater than said pressure head in said cylinder;
• said cylinder having a coupling port for the selected transfer of gas and solution from said replenishment tank;
• first means removably coupling said replenishment tank said coupling port on said cylinder for transferring a selected portion of said pesticide solution, from said replenishment tank to said cylinder;
• and
• second means removably coupling said replenishment tank and said cylinder for transferring pressure from said pressure head from said replenishment tank to said cylinder to create a selected pressure head above said selected portion of said pesticide solution,
• whereby said selected amount of solution of said mixture of pesticide concentrate in water need be manually mixed only once every several days rather than each time said cylinder is replenished and the need to manually operate a hand pump each time said cylinder is replenished is obviated.
