DuPont publishes treatment results for insecticide Dermacor on Intacta RR seeds

DuPont has completed 240 field trials on the 2015-16 crop to evaluate the effects of the seed-treatment insecticide Dermacor on the technologies of Bt soybeans (Monsanto’s Intacta RR). The studies covered the major production regions and compared the relationship between Dermacor and Bt soybeans with the standard adopted controls of the lesser cornstalk borer (Elasmopalpus lignosellus), Phyllophaga cuyabana, the fall armyworm (Spodoptera frugiperda), the velvetbean caterpillar (Anticarsia gemmatalis), and the Helicoverpa armigera.

 

The official registration documents for Dermacor specify a dose of 50 milliliters per 100 kilograms of seed to manage outbreaks of P. cuyabana and the velvetbean caterpillar and a dose of 100 milliliters per 100 kilograms of seed to control the fall armyworm, the lesser cornstalk borer and H. armigera.

 

"The study demonstrates that the sum of the effects of these technologies strengthens the initial protection of soybeans, besides contributing to an increase in yields and profitability for the producer,” stated Érico Cardoso, marketing manager for seed treatment at DuPont Brasil.

 

"The seeds constitute a major crop investment, so it is important for the farmer to adopt the right strategy when using Intacta soybean seeds, which have a high added value,” noted David Tassara, another seed-treatment marketing manager working in Latin America.

 

According to the executives, the results gleaned from the study revealed that a 50-milliliter dose of Dermacor had prevented the loss of 9,000 plants per hectare and a dose of 100 milliliters had saved 13,000 plants per hectare on a crop of Bt soybeans. Under both doses, the results were superior to those of the standard treatment.

 

Dermacor was the first insecticide belonging to a class of anthranilic diamides to be released in Brazil for seed treatment. It is, according to the company, a revolutionary product for the control of soil and foliar plagues. The insecticide has an extended residual effect and high selectivity for pests that create plagues.
