Gansu Farmers Network - Gansu Farmers News October 29 (Expert Li Tingqun) Consultation: I am a farmer in the middle of the county. I have already started to market the autumn sweetpotato. However, the melon strips have grown a lot and are not easy to sell. I haven't seen much improvement when I tried a lot of drugs. What should I do?
Answer: This is caused by gourd virus disease. Symptoms of the disease are the appearance of dark green and light green patches on young leaves, dwarfing plants, shrinking leaves, and late withering or death. Severe diseased leaves on the deformed, chicken-like claws, reduced fruiting melon. The fruit surface has bumps or fruit deformities.
This disease is caused by multiple infections such as cucumber mosaic virus and melon mosaic virus. The virus is mainly wintered on celery, spinach, and perennial weeds, and spread through locusts and seeds. In addition, farm operations and inter-plant friction can also be transmitted through the sap.
Prevention:
1. Use resistant varieties.
2. Seed disinfection. Seed weight 4 prion A powder dressing or soaked with 10% trisodium phosphate for 20 minutes, cleaned and sown after drying.
3. Strengthen field management. Apply base fertilizer; drought, high temperature must be diligently watered to cool and moisten seedlings, promote plant growth and robustness, and increase resistance to disease.
4. Early prevention. In the field at the beginning of the occurrence of locusts timely spraying control. Can choose 50% anti-converse 2000 ~ 3000 times, 40% of dimethoate EC 1000 ~ 1500 times, 5 times of warfarin alcohol 800 times or azadirachtin, matrine and other spray. In addition, 10% of imidacloprid WP can be used 1000 to 1500 times. Although the control effect is good, it should be used with caution because the melon crop is very sensitive.
5. Chemical control. Can be used 20% of the virus A WP 500 times, 1.5% of Virus EC 1000 times, 3% bacteriostatic water agent 300 times or 1.5% of plant disease Ling emulsion 1000 times spray. Once every 7 to 10 days, even spraying 3 to 4 times can ease the condition.

- Only one probe, convenient for carry
- Wireless, convenient for operation
- 4D array scan, very clear image
- High accurate (5% inaccuracies)
- High speed on scan and process (2s)
- Without distortion of mechanical scanning
- More advanced algorithm, more powerful bladder wall recognition technology(High recognition
rate for the bladder wall with air), more accurate contour technology, higher accuracy of
the probe makes scanning results more accurate.
- New algorithm, the measurement results are not subject to the bladder shape and size.
No need to select Gender, Age group and no need to consider special cases such as the effect
of hysterectomy on the measurement results. Good compatibility for different bladders, no
Ubstantial error when measuring small volume or special shape bladders, easier to operate
and use.
- High precision rotary encoder, precise positioning, never need to calibration.
- Waterproof probe
The Sonostar wireless probe is a mini ultrasound scanner without a screen. We minimize the components of a traditional ultrasound into a small circuit board built into the probe, and showing image in smart phone/tablet through Wifi transferring. image can both show in screen and tablet.Image transferring through internal wifi from probe, no need external Wifi signal.
