Phytotoxicity
Phytotoxicity has controversial data. So, in the book "Protection and Protection of the Forest." 1986, issue 1. "The use of pyrethroids and dimilin in the forestry of the USSR and abroad," authors Kuteev F.S., Lyashenko L.I., Puchkova I.I., it is mentioned that deltamethrin in 0.01% concentration caused burns of young leaves of Brussels sprouts. And experiments on beans revealed that deltamethrin at 0, 00175% concentration reduces the accumulation of total and protein nitrogen in leaves for 50 days after treatment and affects the synthesis of ascorbic acid. There is no other data to support this information. But this does not prove the opposite, i.e. it cannot be argued that decis is completely non-phytotoxic.
Attention fake: In Russia, the drug Decis-Profi (deltamethrin) is produced only in 0.6 kg vials and 1 year bags. There is a fake on sale in 2 ml ampoules or 10 ml vials - such products are counterfeit.

Responses
Decis Profi received an average of 7-8 points on a ten-point scale in surveys of florists. High efficiency was noted - it really destroys pests, there is no phytotoxicity, no spots or yellowing were noticed on any plant after treatment (the norms were not exceeded), liquid Decis Profi was easily diluted in water, the smell was weak.
There are disadvantages: low stability in the environment, a short period of protective action (15 days are declared, in fact it can be about 10 days).
