In recent years, with the continuous improvement in wheat harvesting efficiency, a significant amount of straw has been returned to the fields, and wheat bran has also been scattered, leading to an increasing occurrence of wheat scab. Fusarium head blight (FHB) is one of the most destructive diseases affecting wheat crops. The infected wheat heads turn pink, hence the name "head blight." It has been observed that most wheat varieties are highly susceptible to FHB under drought conditions. Especially in high-water and high-fertilizer plots, the disease tends to be more severe. Varieties like Zhoumai 16 and Bainong Dwarf Resistance 58 have shown spike infection rates as high as 10%. Beyond yield loss, FHB causes grain spoilage and deterioration. The toxins produced by the pathogen can also pose serious health risks to both humans and animals.
Wheat scab is a challenging disease to completely prevent. Many farmers do not prioritize planting resistant varieties, and if the disease is not managed in time, it can lead to significant losses. Over the past two years, I've noticed that FHB rarely occurs during the jointing to booting stages but becomes active from heading to full bloom. High temperatures during this period create favorable conditions for the disease. Most farmers lack awareness about scab, don't pay enough attention, and often miss early signs unless they closely inspect the fields. If left unchecked, especially during rainy periods, the disease can spread rapidly, resulting in large areas of dry, white ears within days. Once this happens, it's much harder to control through spraying.
Timely prevention is crucial. Farmers should act as soon as they notice white, dry glumes or red spots on the ears. It’s better to spray early rather than wait. Since FHB is a fungal disease, from the flag leaf emergence to the initial heading stage, 100 grams of carbendazim or 50 grams of oxazole can be mixed with 30 kg of water for effective application. Using a fine mist sprayer and raising the spray boom to target the ears directly ensures even coverage. The interval between applications should not exceed seven days. When the panicles are fully developed and flowering is at its peak, a second treatment is necessary. In cloudy weather or when the disease is severe, an early application during the grain-filling stage can significantly improve control outcomes.
From my field observations, applying just one treatment during the heading to grain-filling period often doesn’t yield good results. Therefore, I strongly recommend that farmers take preventive measures seriously, stay informed, and avoid relying solely on harvest. Proactive management can help reduce losses and increase overall productivity and income.
Premix
The main differences between powder,premixed agent, granule are as follows:
Veterinary Soluble Powder: means a dry powder preparation made of one or more drugs by grinding and evenly mixing, with or without dressing.
Premix: refers to one or more drugs, and a suitable substrate evenly mixed to make a powder or granular preparation.
As a dosage form of feed drug additive, it is specially used for mixed feeding.
Powder powder, that is, powder, and premixed agent, the main differences of granules are as follows:
1.the production method is different
1.powder: medicine or with appropriate auxiliary materials by grinding, evenly mixed dry powder preparation.
2.Veterianary premix: powder or granular preparation made by evenly mixing the drug with an appropriate substrate.
3.granules: raw materials and appropriate excipients mixed into a certain particle size of dry granular preparation.
2.different characteristics
1. Dispersing agent: compared with other solid dosage forms, dispersing agent is easy to disperse, dissolves quickly, absorbs quickly and takes effect quickly; The preparation process is simple, the dosage is easy to control, and it is easy for infants to take.
2.Premix for animal: Premix used in the matrix including carrier, diluent, etc. The substrate should be stable, with good fluidity, and easy to mix with drugs and feed.
3. Granule: the dispersion, adhesion, agglomeration and hygroscopicity of granule are lower than that of granule; The separation of various components in granule is avoided because of the adhesive used to make granule after mixing. Convenient storage and transportation; Particles can change their function by coating.
