If someone gets a splash of pesticide in the eyes, what first aid procedures should be carried out?

What does the term ‘Spray Drift’ mean and how can it be reduced?
in windy weather the pesticide is being sprayed over non target areas like other crops or to hedgerows and water ways which can cause threat to nature and flora and fauna & in some cases long term damage to the environment
Can be reduced by:
1. Avoid spraying in windy conditions and very warm sunny conditions.
2. Use of spray nozzles which produce a minimum of droplets in the drift-prone size range, in particular below 100 microns

- Explain the term pre emergence herbicide application?
it is applied after the crop is sown but before the crop has emerged. The effect of this may be contact foliage, translocated foliage or residual according to the stage of development of the weeds and nature of the herbicide.

What is a systemic acting herbicide?
Systemic/Translocated foliage are absorbed into the plant systems and translocated within the plant via the phloem vessels complete coverage of target plant is not necessary and good control can be achieved with low volume spraying. In the case of herbicides, they move down the root system
A single drop of MCPA can be enough to breach the drinking water limit in a small stream for ___km?
