Platform that integrates genetics with tolerance to an herbicidal asset will help control oat and ryegrass infestations in wheat. Launch takes place at the Show Rural, in Cascavel (PR), between February 3 and 7

TBIO Capricho CL is available for seed multiplication in the 2020 harvest

Integrated Weed Management (MIPD), an essential control tool within the productive system, has been facing difficulties, especially due to the resistance of many species considered enemies of the productive system to various herbicidal assets. Among the reasons for the concern of those who follow the problem, are the losses caused by weed competition, including competition for essential elements such as water, light, nutrients and physical space. In its proper name - Planta Daninha - it already refers to the main reason: it causes damages that reflect in the farmer's pocket. In wheat crops, oats and ryegrass can be responsible for up to 50% of productivity losses, according to data from the ABC Foundation. At the Show Rural Coopavel, an unprecedented technology for the cultivation of wheat in Brazil will be presented commercially, to help growers to control these infestations. TBIO Capricho CL is the first cultivar with Clearfield® technology in the country, the result of a partnership between Biotrigo, developer of the genetic platform and BASF, owner of the technology.

The solution, which is the result of a partnership between Biotrigo Genética and BASF, was created with the aim of solving the problem of resistance of some weed species to ACCase or ALS inhibiting herbicides. According to the doctor in phytotechnics and professor at the State University of Londrina (UEL), Giliardi Dalazen, the technology is already used in wheat-producing countries, such as Canada and Australia. In Brazil, it has excellent results in the rice culture. “This technology will assist the producer in the management of some important weeds in wheat, such as ryegrass, oats and turnips. In the case of ryegrass - the main weed of the crop - the biggest benefit is to control the ryegrass biotypes resistant to glyphosate , ACCase inhibitors (graminicides) and ALS inhibitors ”, he highlights.

Result of genetic improvement

The development of this new cultivar took place at Biotrigo Genética through conventional breeding techniques. André Cunha Rosa, breeder and director of Biotrigo Genética, explains that the process involved crossing a genotype with the CL gene with other genotypes of interest. “ This is not a transgenic event, but an induced mutation in the ALS gene, which provides selectivity to the herbicide imazamoxi in these cultivars”, he comments.

After this crossing, field and laboratory evaluations were carried out to select the important characteristics for the wheat crop, such as yield, industrial quality and resistance to diseases. “We arrived at the development of the first CL wheat after more than 10 years of research and, in addition to being tolerant to the imizadolinone herbicides (IMI), more precisely to the active ingredient imazamoxi, this cultivar also has important agronomic characteristics, such as good resistance level Giberela, Mosaico and Bacteriose ”, he reports. The cultivar is classified as Bread / Improver wheat and has excellent baking performance, has medium / late cycle and medium size. Recommended in regions RS1, RS2, SC1, SC2, PR1, PR2 and for regions of higher altitude in regions PR3, SP2.

Clearfield® System

In Brazil, the Clearfield® system has been used for over a decade in rice. In wheat, it reaches producers as an extremely important tool for the effective control of weeds and to deliver a clean crop for the soy that comes after. According to BASF's Rice and Wheat Marketing Manager, Vitor Bernardes, TBIO Capricho is the first Brazilian wheat tolerant to the post-emergent Raptor® 70 DG herbicide. “The objective of bringing this technology to the Brazilian market is to enable the triticulturist to make an effective control of weeds, one of the great challenges of cultivation. With that, we will contribute to the productivity, quality of grains and the profitability of the farmer in the soy - wheat production system ”, he comments.

Tests

For the technical research manager of the ABC Foundation, Luis Henrique Penckowski, and the researcher of the institution's herbology sector, Eliana Fernandes Borsato, the technology allows the selective use of the Raptor® 70 DG herbicide, in addition to effectively controlling the biotypes of glyphosate-resistant ryegrass and / or ALS inhibitors. “The difficulty in controlling ryegrass with resistance to the herbicide glyphosate was preventing the use of the crop as part of the rotation system. CL wheat and the use of Raptor® 70 DG in the post-emergence of wheat proved to be efficient in tests, making the crop viable because it allows the selective application of herbicides from the imidazolinone group ”, they commented.

Planning the use of technology

The main recommendation is to plan the use of technology on the property and rotate with other conventional cultivars. Giliardi makes recommendations regarding the use of technology. “It is important that this cultivar be introduced in a rotation schedule for cultivars, using it in 25 to 33% of the area cultivated with wheat each year, without repeating it in the same area the following year. Thus, the selection of weed biotypes resistant to the herbicide used will be difficult, prolonging the useful life of the technology ”, warns the professor.

Certified Seeds

Fernando Michel Wagner, commercial manager for Latin America (Latam) at Biotrigo Genética explains that the use of certified seeds is key to the successful use of technology. “The use of pirate seeds disseminates invasive and contaminates crops with weeds, including those resistant to herbicides. For the research to continue bringing tools like this to farmers, it is important that this link in the chain is maintained because private companies like Biotrigo originate resources for research through this source ”, he guides. The manager points out that other cultivars are not resistant to the herbicide, being extremely important that when purchasing Clearfield® wheat, the farmer has the guarantee of origin using the recommended herbicide.

Biotrigo at the Rural Show

During the Rural Coopavel Show, farmers will also be able to check other news such as TBIO Duque, a new bleaching wheat with unprecedented agronomic security in the segment and TBIO Astro, the best type of plant in the TBIO portfolio - which will be available for sale and production in the 2020 harvest, respectively . In addition to the plots with cultivars for demonstration, Biotrigo technicians will also be advising on the indications and management of the crop, in addition to a space prepared for cerealists and cooperatives talking about the process of receiving, cleaning and drying grains. The Biotrigo stand is located on Rua B, close to the poultry building.
