Inatreq™ active is the first member of a new class of cereal fungicides, the picolinamides. It is a Quinone Inside Inhibitor (Qil) and inhibits mitochondrial respiration in fungi by blocking electron transfer in the respiratory chain, binds to complex III (the bc1 complex) at the Qi site (the inner mitochondrial membrane).
Inatreq offers a new solution for control of Septoria tritici where resistance to other chemistries (e.g. strobilurins and triazoles) is a concern.
Inatreq is best used as a protectant treatment or in the earliest stages of disease development.
Inhibition of fungal mitochondrial respiration results in a reduction in the amount of ATP (Adenosintriphosphate) produced. As ATP is the main chemical energy carrier that drives the vital functions of cells, key biochemical processes are distrupted, growth is inhibited and the fungus dies.
The unique target site of Inatreq™ active will be an innovative and effective tool in managing resistance when growers' choices are limited. Target site differs from all other current Septoria actives in the cereal market.
Inatreq™ forms a tenacious deposit on the plant surface. It penetrates into the leaves in small but biologically active quantities. Once in the plant tissue, Inatreq is converted back to the natural product from which it is derived.
Based upon field trials, the following diseases will be controlled effectively by Inatreq at anticipated label use rates.
Laboratory tests show no unreasonable adverse effects from Inatreq™ active:
Testing of Inatreq also indicates that the active ingredient exhibits very low acute toxicity to terrestrial species: mammals, birds, honeybees and earthworms.
