It is currently argued whether the adjuvant or adhesive spreader, which facilitates the dispersion and improves the application of the pesticide, can be classified as an agricultural defensive.
Initially, it should be noted that Article 1, II of Decree 4.074 / 02 provides the adjuvant as: “product used in mixture with products formulated to improve its application”. However, because it does not offer effective pest control and control, many do not consider it as a pesticide.
Such controversy was the subject of the CTA – Technical Committee for the Advising of Agrochemicals (an organ that gathers IBAMA, MAPA, and ANVISA) but has not yet reached a conclusion. There was a previous manifestation defending the maintenance of the registry for adjuvant, since its composition can alter the functioning of the pesticide, before the mixture that is made.
On 03/29/2017, there were some rejections of the adjuvant registration request under the claim “without registration provision in Law 7.809 / 89”.
The CTA through Act 104/2017 does not require registration of adjuvants if there is no proven agronomic effectiveness.
