O Act No. 31 of the Department of Plant Health and Agricultural Inputs of the Secretariat of Agricultural Defense, published this Friday (1/07) in the Official Gazette of the Union, contains the registration of 46 formulated products, that is, agricultural pesticides that will effectively be available for use by farmers. Of these, seven are made from biological ingredients, four of which are approved for use in organic agriculture.
The novelty in biological pesticides is the first record of the parasitoid catolacus grandis to control the boll weevil, the main cotton pest, which has caused damage to plantations in Brazil since the 80s. Registered based on Reference Specification (ER) No. 42, the parasitoid showed excellent pest control results in the field, after experiments coordinated by Embrapa Algodão researcher, Francisco de Sousa Ramalho. The product is called a phytosanitary product with approved use for organic agriculture and can be used in both organic and conventional crops.
Other low impact products are mixtures of Pseudomonas fluorescens with Pseudomonas chlororaphis and a Isaria fusorosea. For organic agriculture, in addition to the parasitoid, there is an isolate of beauveria bassiana, an isolate of Metarhikum anisopliae and a Trichoderma asperellum.
With regard to chemical products, the novelty was due to products formulated based on the fungicide Pidiflumetofen. Four brands were registered in a mixture with difenoconazole and one product with the isolated active. The fungicide is recommended for soybeans, cotton, corn, coffee and a series of crops with insufficient phytosanitary support.
Also included in the publication are three phytohormones and an anti-sprouting agent (1,4 Dimethylnaphthalene), long awaited by the potato processing industry.
The other products use active ingredients previously registered in the country. The registration of generic pesticides is important to reduce market concentration and increase competition, which results in fairer trade and lower production costs for Brazilian agriculture.
All registered products were analyzed and approved by the bodies responsible for health, environment and agriculture, according to scientific criteria and in line with the best international practices.
Currently, Brazil is a world reference in the use of biological agricultural pesticides in the field. In total, there are 552 low-impact products registered since the year 2000.
Products considered to have low impact have biological, microbiological, semiochemical, biochemical, plant extracts and growth regulator active ingredients, and may be authorized in several cases in organic agriculture.
These products are important for agriculture not only because of their toxicological and environmental impact, but also because they benefit crops with insufficient phytosanitary support (minor crops), as these products are registered by pests and not by culture as is the case with chemicals.
With the registration of these seven new products, there are now 43 low-toxicity products for pest control registered in 2022.
