4. INTRODUCTION
 A Sprayer is a device used to spray a liquid.
 In agriculture, a Sprayer is a piece of equipment
that used to spray pesticides on the farm lands.
 These sprayers reduces the human effort.
 Sprayers range in size from man portable range
typically backpacks and spray guns.

5. PROBLEM STATEMENT
 To design and fabricate a proposed model for
automated pesticides sprayer.
 One of the difficult task in farming is to prevent the
crop without any pests.
 This task simply replaced by a Automated sprayer
which reduces the farmer effort.

6. LITERATURE SURVEY
 Performance of a chemical injection sprayer system, found the
time delay of concentrated pesticides through injection sprayers
to be significant, and proposed injection at the individual nozzles
as a possible solution to shorten delays. Development of a direct
nozzle injection system that overcame the concentration
variation problems reported by previous researchers. Simulations
are used to compare chemical application accuracies for various
designs of injection sprayers. They found that reducing the
diameter of the fluid lines near the end of the spray booms
improved overall application accuracy. An autonomous mobile
robot for use in pest control and disease prevention applications
in commercial greenhouses.

12. ADVANTAGES
 A sprayer gives you easy access to these areas by
delivering an efficient coating, all through the squeeze of
a trigger.
 As much as your sprayer is great for coating a surface in
Wet and Forget, it can also be used for leaf fertilizers and
substances to protect plants in your garden.
 Rather than pouring it on and wasting it, you can be a lot
more frugal with your cleaning solution by utilizing a
sprayer that will only allow an appropriate amount to be
released with every squeeze.
 Forget using a sponge or brush of some description, a
sprayer can give you something that any handheld
implement.

13. CONCLUSION
No design is ever perfect for all the time; design needs to be
changed as per the needs and wants of users. Inputs for new
product development and or design improvements are obtained
from the user’s feedback and product evaluation with respect to
user requirements.
 Identify the circumstances under which chemical pesticides
may be required in future pest management.
 Determine what types of chemical products are the most
appropriate tools for ecologically based pest management.
 Explore the most promising opportunities to increase benefits
and reduce health and environmental risks of pesticide use.
