In the rainy season, the combination of moderate temperatures and high humidity in vegetable fields creates ideal conditions for the development and spread of pests and diseases. These environmental factors significantly increase the risk of crop damage, making it essential for farmers to take proactive measures to protect their produce.
According to recent field surveys, several common vegetable diseases and pests are particularly prevalent during this time, including anthracnose, powdery mildew, downy mildew, tomato leaf mold, and the diamondback moth. Farmers across the country should focus on identifying and managing these key threats to ensure healthy crops and minimize yield loss.
**Prevention Recommendations:**
1. **Melon Anthracnose:**
In the early stages of infection, apply 25% chlorothalonil EC diluted at 1000 times, or 50% triadimefon WP at 1500 times, or 40% chlorothalonil suspension at 600 times, or 70% thiophanate-methyl at 1000 times. These treatments help prevent the spread of the disease effectively.
2. **Melon Powdery Mildew:**
At the first signs of infection, use 50% triadimefon suspension at 3000 times, or 99% mineral oil EC (Lycin) at 150 times, or 40% fuberidazole emulsion at 6000 times. Repeat applications every 7–10 days for 2–3 times to maintain control.
3. **Melon Downy Mildew:**
Apply treatments such as 80% mancozeb WP at 2000 times, 72% cymoxanil WP at 1000 times, or 72.2% propamocarb at 600 times. Treatments should be repeated every 7–10 days for 3–4 consecutive applications to manage the disease effectively.
4. **Tomato Leaf Mold:**
Begin spraying at the onset of symptoms, focusing on the underside of leaves. Use 40% fuberidazole EC at 6000 times, or 50% fluopicolide suspension at 1000 times, or 70% thiophanate-methyl WP at 600 times. Repeat every 7–10 days for 2–3 times.
5. **Diamondback Moth:**
During the egg-hatching period, spray with 5% spinosad powder at 1500 times. For larvae control, apply when there are 1–2 larvae per plant before they reach the second instar. Use products like 0.3% azadirachtin at 500 times, 2.5% emamectin benzoate at 2000 times, or 0.6% diflubenzuron at 1000 times. Repeat every 7–10 days for 2–3 times.
6. **Liriomyza sativae (Leafminer):**
Control adult flies by applying 5% spinosad EC at 2000 times during dry, sunny days when adults are active. For larvae, target second-instar stages with 50% imidacloprid WP at 2000 times or 75% thiamethoxam WP at 5000 times. Apply every 5–7 days for 2–3 consecutive rounds.
It is crucial to rotate pesticide use to avoid resistance and follow all safety guidelines regarding pre-harvest intervals. Always read and follow label instructions carefully to ensure both crop health and food safety.
Vtm Test Kit
The generic name of VTM Virus Sampling Tube is a single-use virus sampling tube, which is generally used for the detection and sampling of infectious pathogenic microorganisms in disease control departments and clinical departments. It is suitable for detection and sampling of influenza viruses (including general influenza, highly pathogenic viruses, H1N1 influenza virus, etc.), hand, foot and mouth virus, new coronavirus, measles and rubella and other types of viruses. VTM virus sampling tube can also be used for detection and sampling of Mycoplasma, Chlamydia and Ureaplasma urealyticum.
The virus and related samples in the VTM virus sampling tube should be stored and transported within 48 hours in a refrigerated state (2-8°C). Viruses and related samples can be stored for a long time in -80℃ environment or liquid nitrogen environment. The virus can maintain the activity of the virus in a lower temperature range, reduce the speed of virus decomposition, and improve the positive rate of virus isolation.
The VTM virus sampling tube is generally equipped with a disposable flocking swab. From the appearance point of view, the flocking swab is white and soft. Using this soft brush during the sampling process will make the user feel no foreign body, and it is suitable for different Partial sampling person. Moreover, the flocking swab is designed with a breaking point that conforms to the length of the sampling tube and the natural orifice of the human body, which is not only convenient for sampling but also convenient for transportation of the specimen.
