Agriculture needs Fresh Approach to Tackle Growing Problem of Insect Resistance to Biopesticides, New Analysis finds
Publicado em 13 março 2023
Insect pests which attack crops have extraordinary powers to develop resistance to greener pesticides and a new way to manage resistance risks is needed, according to analysis by University of Stirling scientists.
For more than 70 years, agriculture's response to pesticide resistance has been to seek new pesticides in an endless race to keep up with evolving pests.
Researchers now propose a new way to step off this treadmill as farmers embrace the ongoing green revolution in pest [...]

Researchers analyze performance of bacterium in combating coffee rust
Publicado em 21 dezembro 2022Their research is part basic science, investigating the bacterium's resilience in a hostile environment – coffee leaves – and part biotech, seeing whether the bacterium inhibits the development of a pathogen that causes severe losses to coffee growers. A study supported by FAPESP analyzed the potential of a bacterium for biological control of the fungus Hemileia vastatrix, which causes coffee rust, a major challenge for Brazilian coffee growers. An article on the study is [...]ver notícia -
Review of More Than 1,000 Articles Seeks to Understand How Nanomaterials Affect Plants
Publicado em 17 novembro 2022With the metadata (data generated from the data published in the literature), the authors systematized the knowledge produced collectively to date on the most used nanomaterials, the type of environment to which plants are exposed, the plant organs most exposed to treatments, and the duration of studies. In addition, they calculated the percentages of nanomaterial-based treatments that had positive effects, negative effects and both, as well as those that had no effect on plants. The study [...]ver notícia -
Artificial intelligence helps predict performance of sugarcane in the field
Publicado em 19 outubro 2022October 19, 2022 by Ricardo Muniz, FAPESP A Brazilian study published in Scientific Reports shows that artificial intelligence (AI) can be used to create efficient models for genomic selection of sugarcane and forage grass varieties and predict their performance in the field on the basis of their DNA. In terms of accuracy compared with traditional breeding techniques, the proposed methodology improved predictive power by more than 50%. This is the first time a highly efficient genomic [...]ver notícia -
Husker study: Brazil can grow more soybeans without deforesting Amazon
Publicado em 11 outubro 2022Brazil presents a key example. The country is home to the world’s largest area of rainforest — some 1.2 million square miles, an area more than 16 times the size of Nebraska. The Amazon contains large tracts of rainforests that, when converted to agriculture, release a huge amount of carbon dioxide into the atmosphere, exacerbating climate change. Increasing agricultural production is a national priority for Brazil, the world’s largest soybean exporter. Since the 1990s, [...]ver notícia -
Brazilian Soybean Growers' use of Biofertilizer Examined
Publicado em 29 setembro 2022Using biofertilizer on 80% of their planted area, Brazilian soybean growers are enjoying the environmental and economic benefits of employing the microbiome instead of chemical fertilizers. The microbiome is the community of fungi, bacteria and other microorganisms in a given environment. In farming, it provides the nutrients required by crops and boosts yields. Its use has many economic and environmental benefits. The case of Brazilian soybeans is one of 14 success stories discussed in a [...]ver notícia -
Technique Using Light And Artificial Intelligence Is Effective In Selecting Immature Soybean Seeds
Publicado em 26 agosto 2022Historically based on tradition and experience, the decision-making process in agriculture has been transformed in recent years by technological innovations that scale up production and provide solutions to the challenges posed by pests, natural limitations on arable land and the effects of climate change. Brazilian researchers have developed a technique to help select seeds of soybeans and other legumes in accordance with maturity stages, assuring physiological quality without destroying [...]ver notícia -
North Atlantic temperature helps forecast extreme events in Northeast Brazil up to three months in advance
Publicado em 22 julho 2022The sea surface temperature in the North Atlantic Ocean can be a predictor up to three months in advance of extreme climate events involving reduced rainfall and intense drought in the Northeast region of Brazil. This is one of the main findings of a study by researchers in Brazil, China, Australia and Germany, according to an article published in Geophysical Research Letters. Using a novel methodology based on the concept of precipitation deficit, the study showed that in recent years [...]ver notícia -
Technique Based on Artificial Intelligence Permits Automation of Crop Seed Analysis
Publicado em 22 março 2021In Brazil, researchers affiliated with the Center for Nuclear Energy in Agriculture (CENA) and the Luiz de Queiroz College of Agriculture (ESALQ), both part of the University of São Paulo (USP), have developed a methodology based on artificial intelligence to automate and streamline seed quality analysis, a process required by law and currently done manually by analysts accredited with the Ministry of Agriculture. The group used light-based technology like that deployed in plant and [...]ver notícia -
Application of Potassium to Grass Used as Cover Crop Guarantees Higher-Quality Cotton
Publicado em 17 fevereiro 2021The use of cover crops between cotton harvests protects the soil, conserves water, and reduces the risk of erosion. Researchers at the University of Western São Paulo (UNOESTE) and São Paulo State University (UNESP) in Brazil found that application of potassium (K) to a grass cover crop grown before cotton in sandy soil lowered production cost and resulted in cotton with a higher market value. “The dynamics of early application of potassium to grass planted as a cover crop [...]ver notícia
