  • Hi i bought the product and need to know when should i can apply this, before the light go on (how many hours before ) Or after the light are off ? Should i turn off the fan in the room and is okay if i spray with clear water after i Done the spray with the product pyrethrum ?

    We would advise applying Pyrethrum 5EC just before your lights go out at half the recommended strength on the bottle (2ml per litre) It's fine to keep your fans on, & you can wash off with plain water a few days after the last application.

  • I recently bought Pyrethrum 5ec but when would be best to apply? As in time of day? Before sunset, night or during the day as I believe pyrethrums degrade in UV light.... thank you.

    We would advise using Pyrethrum 5EC during your lights off period.

  • how much ml per litre would I use with the concentrated dosage?

    The Pyrethrum 5 EC dilutes at 4ml per litre, you will get over 60 litres of full strength spray from 1 250ml concentrate.

  • can this product be used repeatedly over the life of a crop? ive a variety of produce from lettuces n herbs to tomatoes and peppers. cheers

    You can use Pyrethrum 5EC once your plants have established roots, right the way through the cycle of your crop until the last 2 weeks.

  • Can i use this product not only as a foliar spray but also as a soil drench? to kill thripes in my soil? can i use even during the middle or end of flowering? Also what preventative would u recommend from the start in order so that dont get these thripes again:) cheers mate

    The Pyrethrum 5 EC can not be applied to the roots, it is to be used as a foliar spray only, it can be applied up to the last but one week. You can use Fungus Gnat Off as a preventative measure in the soil, or alternatively, spray a solution of Neem Repel around the edges or your growing area as a preventative measure.

  • can you use pyerthrum when plants are in flower.

    You can use Pyrethrum up until the last 2 weeks of flowering.
