"Use of amine compounds with improved biodegradability as pesticide adjuvants and fertilizers." The present invention relates to the use of an amine compound, which may be an amine ester or amidoamine based surfactant, with improved biodegradability, as an adjuvant to agrochemically active compounds such as pesticides or fertilizers. the adjuvant has formula (i) wherein R1 represents an aliphatic group containing from 7 to 22 carbon atoms; oil represents an ethylenoxy group; y represents o or nh; R 2 and R 3 independently represent -ch ~ 2-ch ~ 2-oh, -ch ~ 2-ch (ch-3 ~) oh or an alkyl group having 1 to 5 carbon atoms, preferably 1 to 3 carbon atoms; n represents a number between 0 and 10; x represents an o or 1 number, provided that when y is 0 then x will be 1 and when y is nh then x will be 0; and m represents a number from 2 to 6, preferably from 2 to 3, provided that when y is nh, then m will be from 3 to 6, preferably 3; or an adduct obtained by reacting one mole of the compound with 1 to 5 moles of an alkylene oxide having 2 to 3 carbon atoms. ester-amine compounds are obtained from an ethoxylated alcohol which has been carboxymethylated and then esterified with a tertiary hydroxyamine (alkanolamine) and amidoamine compounds are obtained by reaction between a fatty acid or a fatty acid methyl ester and a diamine such as n, n-bishydroxyethyl-1,3-propylenediamine."uso de compostos de amina com aperfeiçoada biodegradabilidade, como adjuvantes para pesticidas e fertilizantes". a presente invenção se refere ao uso de um composto de amina, que pode ser um agente tensoativo à base de éster-amina ou amidoamina, com aperfeiçoada biodegradabilidade, como adjuvante para compostos agroquimicamente ativos, como pesticidas ou fertilizantes. o agente adjuvante apresenta a fórmula (i) em que r1 representa um grupo alifático contendo de 7 a 22 átomos de carbono; eo representa um grupo etilenóxi; y representa o ou nh; r2 e r3 representam independentemente -ch~ 2~ch~ 2~oh, -ch~
