The main diseases that threaten the four-season plants include several common fungal and bacterial infections. Understanding these diseases and their control methods is essential for maintaining healthy growth.
1. **Stem Rot**: This disease primarily affects mature plants, causing the stems to rot at the base. Initially, reddish-brown spots appear on the lower stem, which then develop into water-soaked, translucent lesions. These lesions eventually merge and spread to the petiole base, leading to plant lodging. To manage this, use well-draining soil rich in nutrients, and ensure organic fertilizer is fully decomposed. Avoid overwatering and keep the growing area well-ventilated. In severe cases, sterilize the soil before planting.
2. **Fungicide Application**: At the early stage of infection, apply 70% dexamethasone WP or D-801 powder diluted 600–800 times, or 75% chlorothalonil WP at the same concentration. Spray every 7–10 days for 2–3 applications to prevent further spread.
3. **Gray Mold**: This disease affects stems, leaves, and flowers. Early symptoms include water-soaked spots, followed by gray mold development, which can lead to plant death. Improve air circulation and avoid excessive watering. At the first sign of infection, spray 50% carbendazim diluted 800 times.
4. **Powdery Mildew**: This disease mainly affects young leaves and pedicels, causing white powdery lesions, curled leaves, and reduced flower size. Apply 25% triadimefon diluted 2000 times at the early stage of infection.
5. **Blight**: Common in seedlings, it causes brown lesions on roots and shoots, eventually leading to plant death. Immediately treat affected areas with 65% dixon diluted 800 times, or 600 times Zezin solution. Repeat every 10 days for up to three applications.
6. **Nematode Disease**: This disease attacks the roots, forming yellow-white nodules that shorten internodes, resulting in small leaves and potential plant death. Always disinfect pots and soil before planting to prevent infestation.
7. **Bacterial Spot**: Primarily affects leaves, starting with small brown spots that expand into water-soaked lesions. Remove infected leaves and burn them. Spray streptomycin diluted 5000 times to control the spread.
By following these preventive and treatment measures, you can significantly reduce the risk of these diseases and maintain a healthy, thriving garden. Regular monitoring and timely intervention are key to long-term success.
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.
