INTRODUCTION

• The need for applying chemical plant protection
  processes
• To get the necessary minimum amount of active
  agents into the environment
• What is necessary to prevent the diseases from
  spreading, with the least possible environment
  burden
• Problem in spite of the environment friendly
  work-methods and the significant pesticide and
  other cost reduction the modern plant protection
  technologies have not been widespread in
  Hungarian practice.
• Necessary experiments to promote the widespread
  of the new modern plant protection technology in
  Hungary
• Experiments in the frame of NSRF (National
  Scientific Research Fundation) project
• The Possibilities of Reduction of Pesticides by
  Spray Technology number T-042594

Objective of the research work

• To promote widespread of chemical reducing
  environment friendly and chemical saving by
  verifying the advantages of work quality
  parameters of the new modern spray technology
  methods.
• The direct objective of the examination to
  verify the advantages of applying the plant
  sensor in cherry plantation.

Work principle of the plant sensor
The infrared sensor gives signal if it senses
leafy crown or trunk and depending on speed it
begins spraying

Questions of spraying

• What?
• What against?
• Which pesticide?
• In which quantity?
• Which sprayer?
• When?

8
The basic duty of spraying

• Suitable agent should get to the target surface
  in the appropriate
• Time
• Quantity and
• Distribution

9
The principle of sustainable development in plant
protection

• To get the necessary least quantity of chemicals
  into the environment
• Causing the least environmental burden that is
  possible
• So as to prevent the spreading of disease

10
EXAMINATION METHOD

• The character of the examination
  comparison examination
• To be completed examinations
• determination of coverage characteristics, and
• control of pesticide saving.

11
Steps of the coverage examination

• Recording the examination circumstances,
• Presentation of the examined machines,
• Description of target surface, plantation,
• Recording the parameters of machine setting,
• Placing water sensitive test papers,
• Completing spraying operation,
• Collecting the test papers,
• Determining the coverage characteristics, and
• Evaluation of examination results.

12
The steps of controlling pesticide reduction

• Recording the examination circumstances,
• Filling up the tank with the given amount of
  pesticide,
• Spraying the pesticide,
• Re-measuring the remaining pesticide,
• Measuring the section length of the sprayed
  plantation with the given amount of pesticide,
• Determining the pesticide doses,
• Evaluation of examination results

13
Recording the examination circumstances

• Character of exam comparison examination
• Place of exam AGROROYAL Kft., Heves
• Date of exam 26 July 2007
• Machines used KERTITOX BORA equipped with
  plant sensor VULKANO without plant sensor

The characteristics of the examination

• Examined area
• cherry plantation
• lane distance 6 m
• stem distance 4 m
• age 2 and 3 years
• Weather parameters
• air temperature 24-26 oC
• wind speed 0.4 0.9 m/s
• relative humidity 41-43

CONCLUSIONS

• KERTITOX BORA ensured more favourable work
  quality values than the VOLCANO spraying machine.
  
• Applying plant sensor without a significant
  change of the coverage characteristics,
  meaningful liquid and pesticide savings can be
  obtained in loose lined young plantation as well.
• The advantages of the modern spray technic can be
  adapted in field experiments technology too.
