How often do I need to spray Pyrethrum for it to be effective. Regards John
We would recommend you to spray at 7 day intervals.
can pyrethrum 5ec b used on conifer hedges or is there an alternative product that would better suit. thanks. jon
This product can be used on conifer hedges, but if you are using to get rid of insects, we would advise you to spray when the insects are visible, as it kills by contact action.
To mix?, is it 5ml per litre?.dave.
The correct dilution rate is 4ml per 1L of water (20ml to 5L of water).
Saadi Karami, Zardband Pharmaceutical Co., Iran Hello I want Pyrethrin (Pyrethrum extract) for Insecticidal research. I had a few question about this field: 1) For prepare serials dilution of this product what solvent should be used? 2) Is the possibil
We would like to advise you to use water to dilute, and not to mix with anything else, including Neem Oil. The price is shown on the product information. The concentration of Pyrethrin is 5%. Unfortunately, we do not deliver outside the UK, therefore we would not be able to deliver to Iran.
