For -the practical use of the weed-killer cornposition acçording to the invention in agriculture, the antidotes of formula (II) (and those of formula III) are mixed with the weed-ki]lers of formula (I) and with inert substances and adjuvants in suitable formulae, accordin~ to the technique known~to the expert in the field, to obtain, for example liquid solutions emulsifiable i.n water, water-dispersible pastes, wettable powders and ~ranular mixtures.
- J 1 6~056 In the formulae ready for agricultural use, it is also possible to add other active weed-1~iller compounds with complementary or adjuvant action, forming part of the S-tri-azine group (e.g. Atrazine* Si111azine~* Cyanazine*etc.), a 05 Thiolcarbamate (e.g. 13ut:ilate*, EPTC, Vernolate* etc.), a substituted urea (e.g. Linuron* ~lethaben7tia7uron* etc.) or other acetanalides or wee(l-killers.
The use of the composition accordin6 to the invention may take place through distribution with conventional ma-cllines before maize planting, possibly followed by lightincorporation to the soil and by planting (pre-seeding treatment incorporated), or may be effected after planting, but beÇore emergency of the cultivation (pre-emergency treatment), or even after said emergency but always on lS infested grass in the first stages of development (post-e-mergency treatment).
It is possible to distribute, according to the type of weecl-killer used and the relevant antidote, from 0.25 to lO
Kg/11a of total active substances.
The Eollowing examples illustrate the invention more fully without limiting tlle same.
