Manejo de doenças e portfólio da BASF em arroz - Planfer

Summary

This video script captures a tour led by Antônio Brandão, an agronomist from BASF, focused on rice cultivation in Rio Grande do Sul. Brandão discusses key practices in disease management, product recommendations, and the importance of certified seed treatment. He emphasizes the role of fungicides, herbicides, and crop rotation to combat resistance issues and improve rice quality. He also addresses the challenges of late planting, the significance of planting timing, and the need for consistent product rotation to prevent resistance buildup, highlighting BASF's commitment to sustainable agricultural practices.

Takeaways

• 😀 The presentation focuses on the management of diseases and portfolio of BASF's rice products.
• 😀 The speaker emphasizes the importance of certified seed treatment, especially for crops in Rio Grande do Sul, and encourages the use of certified seeds for better yield and disease resistance.
• 😀 Fungicides and herbicides play a critical role in managing rice diseases and resistance, with specific recommendations for products like Bril and Bim.
• 😀 Two popular rice varieties in Rio Grande do Sul are Guri (from BASF) and 24 (from IRGA), each with its strengths and weaknesses regarding disease resistance.
• 😀 The speaker stresses the importance of early planting to minimize disease risks. Rice planted later in the season is more prone to issues.
• 😀 There is an ongoing issue with herbicide resistance in rice farming, specifically with imazetapir. The speaker encourages revisiting herbicide application strategies.
• 😀 The speaker advocates for using pre-emergent herbicides like Herbadox and Gamit to control weedy rice and other invasive species.
• 😀 BASF recommends rotating Clearfield rice with soybeans or conventional rice every two years to manage resistance effectively.
• 😀 The upcoming launch of BASF's Provisia technology aims to address herbicide resistance in rice, with a projected release between 2018 and 2019.
• 😀 A key recommendation for managing rice diseases is to apply a combination of Bril and Bim fungicides in three applications: one at early booting, and two more spaced 15 days apart.

Q & A

What is the primary focus of the station presented by Nton Brandão?

The primary focus of the station is on disease management and the portfolio of BASF, specifically discussing the rice cultivation process and related management practices.

What are the key steps emphasized for rice management in the Rio Grande do Sul region?

The key steps emphasized include the use of certified seed treatment, maintaining a strong plant stand, and proper fungicide and herbicide application to control diseases and pests.

Why is it important to follow the seven steps for rice cultivation in Rio Grande do Sul?

Following these seven steps is crucial to improving the overall quality and productivity of rice crops in the region. These steps help ensure effective disease management, resistance control, and optimized rice growth.

What are the two most commonly planted rice cultivars in Rio Grande do Sul, and how do they differ?

The two most commonly planted cultivars are Guri from BASF and 24 from IRGA. Guri is more susceptible to bruzone, but it has high quality for milling and good productivity, whereas 24 is more resistant to bruzone.

What is the recommendation for fungicide application when planting the Guri cultivar?

The recommendation for fungicide application on Guri is to use a combination of BRIL and BIM to manage diseases like rice blast. These products help control issues effectively in the early stages of crop growth.

What is the recommended approach for herbicide application to control weed resistance in rice fields?

To control weed resistance, it is recommended to rotate herbicides and use a combination of pre-emergent and post-emergent products like Herbadox and Gamit. This helps manage weed issues effectively and prevents the development of herbicide resistance.

How can farmers manage capim arroz (barnyard grass) and red rice effectively?

Farmers should use pre-emergent herbicides like Herbadox and Gamit, along with post-emergent treatments, to control capim arroz and red rice. This combination helps to alleviate the issues and ensures better weed control.

What does the speaker suggest about the use of products like Propanil in the management of barnyard grass?

The speaker suggests that returning to the use of products like Propanil, which were previously discontinued, may be necessary for better control of barnyard grass, as the herbicide can be effective in tackling resistant weed species.

What is the potential impact of overuse of herbicides like Imazetapir, as mentioned in the script?

Overuse of herbicides like Imazetapir has led to resistance in certain weed species, resulting in fields being left uncleaned, as farmers have not applied the recommended number of applications, contributing to the spread of resistant weeds.

What is the timeline for the release of a new BASF product designed to combat red rice resistance, and what challenges are involved?

The new BASF product designed to combat red rice resistance is expected to be released around 2018-2019. However, the release depends on governmental approval and regulatory processes, which can influence the timeline.
