What are EC, SC and other pesticide formulations?

EMULSIFIABLE CONCENTRATE (EC)

• It is most active form and highly reactive.

• It comes in transparent liquid form.
• When mixed with water, it becomes white. 
• It is easily soluble and no need to stir.
• It is not advised to mix any chemical in it.
• These are cheaper than SC form of pesticides.
• The active ingradients are dissolved in organic solvants such as xylene and cyclohexane.
• These solvants are not soluble in water, so there is need to add emulsifiers to make them soluble, in water.

SOLUBLE/ SUSPENSION CONCENTRATE (SC)

·        It is supposed to be best for among pesticides to be used.
·        The active ingredient is ground to fine powder of about 5 micron.

·        It is liquid dense form, white in colour.
·        Chemical is remain safe in it, because of mixing of wettable powder.
·        It is less soluble and need to stir little and affects for long time on crops.
·        Due to mixing of wettable powder in it, it sticks to leaves and gave results 

         for long time.

 
WATER SOLUBLE GRANULES (WSG)

·        It comes in solid form (Round apple shaped).

·        Particle size range from 300-1700 micron.
·        Easily soluble in water when mixed or put in water with in 1 minute.
·        These may be white or grayish white in colour.
 
WETTABLE POWDER (WP)

·      It comes in powder form, particle size about 25 micron i.e. Coarse 

          powder not fine.

·        It is less soluble in water.

·        If particle size is 10 micron, then these are called dustable powder.
 
SOLUBLE POWDER (SP)

·        It comes in fine powder form
·        It is soluble in water easily.
 
WATER DISPERSIBLE WETTABLE GRANULES (WG)

·        Brownish dirt colour coarse powder.
·        It is soluble in water.
·        These are dispersed on leaves effectively when sprayed with water.
 
CAPSULE SUSPENSION (CS)

·        It comes in granule form.
·        The Granules degrade slowly on the leave and affects for long time.
 
SOLUBLE LIQUID CONCENTRATE (SL)

·        It looks like EC.
·        Easily soluble.
·        But, It does not show any colour on mixing with water.
 
GRANULES

·        It looks just like Sugar or Urea.
