Thrip control in greenhouse.
If you are treating for thrips, you will use 8 oz. (4 x 2 oz packs) of Orthene 35 WP in 100 gallons of water. The product is for commercial greenhouses not for residential use. The smallest amount that could be used would be 1 x 2 oz pack in 25 gallons as there is not a way to breakdown the packs into smaller amounts. Tristar 8.5 or Avid would be better options that can be mixed down in smaller quantities.
