How To Calculate Mixing Ratios Of Pesticides
If you are using chemical pesticides that are non organic that you purchased from a store then you will have to calculate the mixing ratio defined by the manufacturer. Reading the label will explain the specific ratio of pesticide that you need to mix with water as a ratio. As an example, dilute one part chemical with five parts of water and stir vigorously. One part chemical makes 6 parts of diluted pesticide mixture.
This tells you that the mixing ratio is 1 part pesticide + 5 parts water = 6 parts mixture.
The pesticide is 16 of the total pesticide mix
The water is 56 of the total pesticide mix
Or the label might say, prepare the spray by mixing 250 millilitres of pesticide in each 10 litres of water.
Use 5 litres of spray to cover 100 square metres.
Hint: 1 L = 1000 mLs
This tells you that the mixing ratio is 250 parts pesticide + 9,750 parts water = 10,000 parts mixture.
The pesticide is 102,50000 of the total pesticide mix
The water is 190,7,05000 of the total pesticide mix.
It may be best to have a calculator hand when figuring out your specific mixing ratio. You don't want to inadvertantly make the mix to strong or not strong enough.
