Study indicates low availability of seed treatment products in Brazil

Despite accounting for more than 2,000 registered formulated products (FP), Brazil has a low availability of seed treatment (ST) products for some crops and unwanted biological targets. This is the conclusion of a study released by Abrasem, the Brazilian Seeds and Seedlings Association.
No fewer than 98% of the seeds of hybrid corn and 70% of soybean seeds are treated in Brazilian agriculture. It is the seed treatment that allows the control of biological targets in the early stages of the crop, since many pathogens remain in the soil, such as, for example, fusarium and sclerotinia.
The adoption of TS more than doubled in six years as the market value jumped from 360 million dollars in 2009 to 870 million in the 2014-15 harvest, showing great growth and its perception of value by farmers, according to data from Abrasem. According to the study, however, such control is "threatened by the low availability of products".
To treat insects found in the seeds of corn, cotton, wheat, peanuts and rice, the products available belong to the same mode of action, "which fatally increases the continuous pressure of resistance selection of pests and diseases," according to the research: For many crops with less economic impact, the situation is even more serious, with little or no availability of phytosanitary products for such treatment. These facts make it difficult or impossible for the rotation of phytosanitary products and, consequently, resistance management".
According to official data, there are 82 products registered for the purpose of seed treatment, including FP based on carbofuran: For the soybean crop, 61; for maize, 52, for beans, cotton and wheat, respectively, 44, 42 and 39 formulated products are registered for TS. For the peanut crop, 18 products; irrigated rice, 6 products; melon and watermelon only one and for papaya, for example, no product.
"In view of the fragility scenario in the availability of phytosanitary products for seed treatment, both for crops of great economic representativeness and for crops of lesser importance, adjustments are necessary to correct this dysfunction, due to the impossibility of practicing the rotation of products and the correct management of pest and disease resistance", noted the Abrasem study.
