Grapegrower insights on cutting-edge botrytis control wanted! Researchers are seeking input from growers through a survey to gauge their interest in adopting RNAi-based biopesticides, a promising new crop protection technology. The survey is part of a research project led by Curtin University under the Australian Research Council (ARC) Research Hub for Sustainable Crop Protection, with Wine Australia as a funding partner. The survey takes approximately 20 minutes to complete. The results will help guide researchers, government, and industry working on RNAi-based biopesticide technology development and implementation. The survey can be found at the following link: https://lnkd.in/gnxcJR55 The ARC Research Hub brings together experts from research institutes and industry to advance UQ’s BioClay™ technology, which uses RNA interference (RNAi) to protect crops. This biodegradable, non-genetically modified solution involves the topical application of RNAi via clay particles to inhibit pest and pathogen growth by disrupting essential protein production. The research, which includes trials targeting botrytis in grapevines, has shown promising results. If successful, RNAi-based biopesticides could offer a sustainable solution to fungicide resistance and enhance long-term disease management. #aussiewine #wineresearch #viticulture #winegrowing #grapegrowing #australianwine Curtin University Australian Research Council Wine Australia

Getting to know Tar Spot - Tar spot is a fungal disease that affects corn plants, caused by the fungus Phyllachora maydis. It shows up as small, raised black spots on the leaves, husks, and stalks of the corn plant. These spots can grow and merge, which damages the plant's ability to perform photosynthesis, the process plants use to convert sunlight into energy. When photosynthesis is reduced, the plant becomes weaker and produces less grain, leading to lower yields. In severe cases, tar spot can cause the leaves to die early and can even kill the plant, resulting in significant economic losses for farmers. The disease thrives under specific environmental conditions, particularly in areas with high humidity and frequent rainfall. Warm temperatures combined with prolonged leaf wetness create an ideal environment for the fungal spores to germinate and infect the corn plants. Fields with dense canopy cover that retains moisture are especially vulnerable. The disease is more prevalent in regions with extended periods of dew and high nighttime humidity, which facilitate the spread and persistence of the pathogen. The lifecycle of tar spot begins with the overwintering of fungal spores in infected crop residue. In the spring and summer, these spores are released into the air and carried by wind or rain to new plants. Once on a susceptible corn plant, the spores germinate and penetrate the leaf tissue, developing the characteristic black tar spots. The fungus continues to produce new spores, which can infect neighboring plants, perpetuating the disease cycle. Effective management of tar spot includes crop rotation, residue management, and selecting resistant corn hybrids, along with timely fungicide applications to reduce the disease's impact.

Here is some more info about Tar Spot. It’s nice to know not only what to look for, but knowing what it does to the plant is also important. We will continue to learn more and more about this disease to be more effective when it does appear.

Artwork painted by the maize root microbiome 🦠🎨 ⌬ Benzoxazinoids are a class of indole-derived plant metabolites that function in defense against numerous pests and pathogens. 🔎 Benzoxazinoids play a direct role in shaping the rhizosphere microbial communities. 🔬 MBOA (6-methoxy-benzoxazolin-2-one) is a bioactive compound of maize with a half-life of several days that can be further metabolized to reactive aminophenols by specific soil microorganisms. ↔️ When soil microbes break down these compounds into aminophenoxazinones, they develop allelopathic properties that suppress the germination and development of neighboring plants. 📰 A recent study by Thoenen et al. 2024 demonstrated that maize root bacteria are adapted to metabolize the specialized metabolites of their host. 🧫 By systematically screening for BX-tolerant bacteria, researchers can identify potential candidates for developing more effective plant growth-promoting (PGPR) inoculants specifically tailored for maize cultivation.

Check it out! We’ve found that the 𝐠𝐫𝐞𝐞𝐧 𝐩𝐞𝐚𝐜𝐡 𝐚𝐩𝐡𝐢𝐝, 𝘔𝘺𝘻𝘶𝘴 𝘱𝘦𝘳𝘴𝘪𝘤𝘢𝘦, is becoming less sensitive to 𝐬𝐞𝐥𝐞𝐜𝐭𝐢𝐯𝐞 𝐢𝐧𝐬𝐞𝐜𝐭𝐢𝐜𝐢𝐝𝐞𝐬, which are specifically designed to target only plant-sap sucking insects such as aphids, making them compatible with biocontrol agents. We discovered that two specific aphid genotypes that dominated 𝐃𝐮𝐭𝐜𝐡 𝐬𝐰𝐞𝐞𝐭 𝐩𝐞𝐩𝐩𝐞𝐫 𝐠𝐫𝐞𝐞𝐧𝐡𝐨𝐮𝐬𝐞𝐬 in 2019 and 2022 are less sensitive to the selective insecticides 𝐩𝐲𝐦𝐞𝐭𝐫𝐨𝐳𝐢𝐧𝐞 and 𝐟𝐥𝐨𝐧𝐢𝐜𝐚𝐦𝐢𝐝, when compared to other aphid genotypes from the same crop system. These insecticides were the main insecticides used to control 𝘔. 𝘱𝘦𝘳𝘴𝘪𝘤𝘢𝘦 in these years. Interestingly, no resistance has been reported yet to these insecticides. Our results, however, indicate that insecticides likely play a role in selecting for the dominant genotypes of 𝘔. 𝘱𝘦𝘳𝘴𝘪𝘤𝘢𝘦 in conventional greenhouses. 𝘔𝘺𝘻𝘶𝘴 𝘱𝘦𝘳𝘴𝘪𝘤𝘢𝘦 genotype 𝐌𝐋𝐆-𝐑, which caused 𝐦𝐚𝐧𝐲 𝐢𝐧𝐟𝐞𝐬𝐭𝐚𝐭𝐢𝐨𝐧𝐬 in conventional Dutch sweet pepper greenhouses in 2022, showed reduced sensitivity to both pymetrozine and flonicamid, but also carries mutations linked with resistance to other insecticides (pyrethroids, carbamates, and neonicotinoids). Our findings indicate that controlling these aphids with insecticides may become harder, emphasizing the need for pest management strategies that prioritize biocontrol and minimize chemical insecticide use for sustainable agriculture and environmental and organismal health.

Arbuscular mycorrhizal (AM) symbiosis plays a significant role in controlling root parasitic plants, particularly under low phosphorus conditions. In nutrient-poor environments, plants increase their production of strigolactones, which are signaling molecules that stimulate the germination of root parasitic plant seeds. These parasitic plants rely on strigolactones to locate and infect host plants, thereby compromising the health and yield of crops. When plants form a symbiotic relationship with AM fungi, a shift occurs in their metabolic processes. The presence of AM fungi often leads to a reduction in the production of strigolactones. This decrease is crucial because strigolactones are also involved in the signaling pathway that triggers the germination of parasitic plant seeds. By lowering the production of these signaling molecules, AM-colonized plants effectively diminish the germination and subsequent infection of parasitic plants. The reduction in parasitic plant infection has a direct positive impact on plant fitness and agricultural yield. With fewer parasitic plants competing for resources, the host plants can allocate more energy and nutrients to growth and reproduction, leading to improved crop performance and yield. In summary, AM symbiosis provides an effective biological control mechanism against root parasitic plants. By reducing strigolactone levels, AM fungi decrease parasitic plant germination and infection, thereby mitigating the harmful effects of these weeds and enhancing plant productivity. . . . . . . . . . . . . . . . •name :- abhi baraiya •mail I'd:- abhibaraiya94@gimail.com . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . #ai #agri #bio #organic #fertilizer #vam #controlreleasefertilizer #soilmonitoring #EcoAgriculture #BiologicalFertilizers #GreenFertilizer #Microbiallnoculants #agriculture #Innovation #Technology #Future #sustainability #productivity #businessintelligence #artificialintelligence #automation #food #sustainable #export #import

THE VALUE OF SOIL AMENDMENTS Many micronutrient deficiencies can be remedied through foliar or soil applications of amendments. Zinc, iron, and boron deficiencies can all be addressed through foliar applications of micronutrient-rich amendments. At ST Biologicals we recommend the nanoparticle micronutrient products from AquaYield.com. These products are foliar sprays and more effective than the micronutrients themselves. So, you need less inputs, saving dollars and improving the bottom line. We also recommend adding a biostimulant to your input mix. With microbes active in your soil, plants are more resilient against drought, salty conditions, heat, and other abiotic stresses. Healthy plants have fewer pests and less disease issues. AMENDMENTS NEED MICROBES FOR THE BEST RESULTS Most micronutrients need to change form before they’re plant available. Synthetic sources of micronutrients especially need the help of an active microbial community. The vast majority of bacteria, fungi, nematodes, and many other microscopic organisms are beneficial. We’ve studied the bad guys (pathogens) because they have an obvious impact on plant yield. But the pathogens wouldn’t have a chance if your agricultural practices favored microbiology in general. A strong microbial community will outcompete the pathogens, especially if you give them a hospitable environment. Micronutrients are food for microorganisms. Plants also supply food as plant exudates. Microbes repay plants by giving them the micronutrients in the forms the plants can use the most efficiently. There’s no downside to nurturing your microorganism communities. Want to banish Phytophthora from your fields? Discontinue fungicide use and add biostimulants to your routine. At ST biologicals we recommend the products from PurpleCowOrganics.com. Their products jumpstart your microbial populations so pathogenic fungi and bacteria can’t get a hold of any soil real estate.
