Focus on crop diseases: Charcoal rot disease 🔎🌿 🔬 Macrophomina phaseolina is a devastating soil-borne fungal pathogen that causes charcoal rot disease, particularly impacting major crops under drought and high-temperature conditions. 🦠 The pathogen demonstrates remarkable survival capability through microsclerotia (desiccation-tolerant survival structures formed by compact threads of hyphae), which can persist in soil and crop residue for several years, making traditional control methods challenging. 🌾 Its broad host range includes economically important crops such as soybean, corn, sorghum, and numerous legumes, where it typically causes wilting, stem rot, and premature plant death. 🔎 Host colonization patterns show a preference for vascular tissue, where the pathogen disrupts water transport systems, leading to characteristic black microsclerotia formation that gives the disease its common name. 📈 The fungus releases cell wall-degrading enzymes and toxins to colonize host tissue, while drought stress (especially late-season droughts) and high soil temperatures (30-35°C) significantly enhance disease development. 🌡️ Climate change scenarios predicting increased temperatures and drought frequency may expand both the geographical range and disease severity. 👨🌾 Disease management requires an integrated approach combining resistant varieties, cultural practices to reduce soil inoculum, biocontrol strategies (e.g. use of Bacillus amyloliquefaciens, Bacillus clausii & Trichoderma harzianum) and minimizing plant stress, as chemical control alone has shown limited effectiveness.

Alternaria is a genus of fungi known for causing significant plant diseases, affecting various crops. Key diseases include Alternaria leaf spot, which impacts tomatoes, carrots, and brassicas; Alternaria blight, affecting canola and wheat; and fruit rot, notably in tomatoes and peppers. These infections can lead to reduced yield and quality. Environmental factors like humidity and temperature influence Alternaria prevalence, making effective management strategies—such as crop rotation and fungicide application—essential. Understanding these pathogens is crucial for maintaining crop health and ensuring agricultural productivity.

Are Bananas Going Extinct? 🍌🚨 For 40 years, the Cavendish banana has been the world’s go-to variety, prized for its disease resistance. It was the answer to the Fusarium TR4 fungus outbreak in the 1950s. But now, Fusarium wilt—also known as Panama disease—has resurfaced, affecting 20 Latin American countries. This fungus triggers the plant's self-defense, leading to the formation of tylose, a gel-like balloon that blocks water and nutrient flow, ultimately killing the banana plant. Is the Cavendish banana facing extinction? The industry is on high alert as it battles this persistent threat. https://lnkd.in/exS9kDJz #BananaCrisis #CavendishBanana #FusariumWilt #Agriculture #FoodSecurity

👉 Here are some common fungal diseases of rice: * Blast (Magnaporthe oryzae): It causes lesions on leaves, stems, and panicles, leading to reduced yield and quality. * Sheath Blight (Rhizoctonia solani): It affects the sheath tissue, causing lesions that expand and eventually lead to plant death. * Brown Spot (Bipolaris oryzae): Characterized by oval to spindle-shaped lesions with brown centers and yellow halos, it affects leaves and can reduce yield. * Rice Rust (Puccinia spp.): It causes orange to reddish-brown pustules on leaves, affecting photosynthesis and reducing yield. * False Smut (Ustilaginoidea virens): This disease forms greenish to blackish spore balls on rice panicles, leading to yield loss and reduced grain quality. * Bakanae Disease (Fusarium moniliforme): Also known as "crazy rice" disease, it causes seedlings to grow tall and thin, leading to weakened plants and yield loss. These are just a few examples of fungal diseases that can affect rice crops. Preventive measures such as proper field management, crop rotation, and resistant varieties can help mitigate their impact. #IRRI #agriculture #Ipm

Did you know that #soil treated with a blend of 1,3-D (TELONE™) and chloropicrin and can help improve your soil beyond the benefit of targeting plant parasitic nematodes and soil-borne diseases? Research shows that beneficial root-colonizing bacteria Bacillus and Pseudomonas—which produce plant-active hormones—increase dramatically with both soil fumigants. In other words, using a TELONE™/pic blend ahead of planting helps target destructive plant parasitic nematodes—allowing developing roots to thrive—while allowing beneficial bacteria to flourish! Now that's a win-win. Want to learn more about TELONE™ and soil health? Check out the full article, here: https://lnkd.in/ghz8Cpt4

"Same Same But Different". I thought that what I should match with this quote. Suddenly I visited chilli plots and I got the answer to my question. So look what I got to match this quote........i.e.'Leaf curling' ✨ Generally we see that leaf curling in plants It may be due to different reasons. But in the chilli plant it is mainly because of Mite infestation/Thrips infeastion/Cilli leaf Curl Viral Disease 🦠. Let's explore it......🕵️ 🔰Mite Yellow mite➡️Polyphagotarsonemus latu🕷️ ❇️Symptoms:- √ Downward curling and crinkling of leaves. √ Leaves with elongated petioles. 🔰Thrips :- Chilli thrips➡️Scirtothrips dorsalis🪰 ❇️ Symptoms:- √ The infested leaves develop crinkles and curl upwards. √ Buds become brittle and drop down & elongated petiole. √ Early stage, infestation leads to stunted growth and flower production, fruit set are arrested 🔰Cilli Leaf Curl Disease Pathogen➡️ Chilli Leaf Curl Virus 🦠 ❇️Symptoms:- √ Chilli Leaf Curl Virus are characterized by upward curling of leaf margins, yellowing of veins and reduction of leaf size. √ Additionally, leaf veins become swollen with shortening of internodes and petioles. Older leaves become leathery and brittle. √ If plants are infected during the early season, their growth will be stunted, resulting in significant yield reduction. √ Fruit formation in susceptible cultivars is rudimentary and distorted. √ The virus causes similar symptoms as the feeding damage of thrips and mites. √ White Fly is the most prominent vector for spread. #PlantsHealth #Plantprotection #Diseasediagnosis #Chilliproduction #Plantdoctor Agriculture Today Group The Farmer Agri (The Family Farm) World Agri-Tech World Agriculture Forum World Vegetable Center ICAR- Indian Council of Agricultural Research ICRISAT East-West Seed Plant Protection

Might orange juice 🍊 be about to disappear from supermarket shelves for good? Maybe, unless world agricultural authorities get their act together.   All over the world, citrus crops face the threat of #Huanglongbing (HLB), a bacterial disease that decimates orchards, and the disease’s relentless expansion is leading growers to fear the worst. Billions of dollars have been lost across affected countries, and further billions have been invested over the last two decades to combat the disease worldwide, but no lasting solution has been found.   At present, of the world’s major citrus-growing areas, only the Mediterranean basin and Australia are free of the disease, which is transmitted by two insects of the psyllid family.   In an article published on The Conversation France, a group of #CIRAD scientists take stock of the rapid development of #HLB, also known as “citrus greening” and "yellow dragon disease", and the advances made in research to combat the epidemic.   Read more 👉 https://lnkd.in/dVXjSGPM Ministère de l'Enseignement supérieur et de la Recherche Ministère de l'Europe et des Affaires étrangères TropicsafeEU PHIM Plant Health Institute Montpellier INRAE CORSE

We have reached the top of the Plant Health Pyramid! 🔺 Q: What is the fourth step of the Plant Health Pyramid? A: We’ve made it to the end on our Plant Health Pyramid educational segment! 👏 🌱 Level 4 is characterized by plants producing higher levels of secondary metabolites, which are compounds that plants generate for 💪 self-defense, such as flavanols, phytoalexins and biflavonoids. Many of these compounds are well-known to us because they possess strong properties that humans use in medicine, including caffeine, nicotine and morphine. These compounds often have potent anti-bacterial and anti-fungal effects and can shield plants from UV rays, ☀️🦗 insects, and diseases. However, they require significant energy to produce, meaning the plant must have progressed through the earlier 3 levels of health to have enough energy to generate these compounds in much larger quantities than usual. 🌾 To reach level 4, it's necessary to have a rich and varied microbiome, both in the soil and on the surface. The right microorganisms help activate the plant's immune system and stimulate the production of higher levels of secondary metabolites. It's crucial that the microbiome consists of beneficial, disease-suppressing microbes rather than harmful, disease-promoting ones to achieve this strong immune response. When you achieve the fourth step of the pyramid, plants become resistant to chewing insects, like corn earworm beetles, stink bugs and nematodes. Plants may also become resistant to viruses that they are exposed to. 🌟🔺 For a more thorough explanation of the Pyramid, visit https://lnkd.in/gPh8VQFi **Photo borrowed from the Advancing Eco Agriculture website and all ownership of the graphic go to John Kempf and Advancing Eco Agriculture. #planthealth #planthealthpyramid #sustainableagriculture #nitrogenmanagement #cropresilience #agronomy #soilhealth #ecofriendlyfarming #agriculturalscience #cropnutrition #plantscience #farmingpractices #microbialactivity
