The pest has a wide distribution across China, with 3 to 4 generations per year in regions like Shandong. Both adult and larval stages feed on asparagus shoots or the outer layer of the plant, causing significant damage. This feeding can result in malformed bamboo shoots, or the shoots may become short and deformed, with abnormal branching or leafy clusters. In severe cases, the affected plants may die.
For prevention and control, several methods are recommended. First, during early winter or early spring, it is important to clean the fields by removing dead branches and leaves, and burning them to destroy overwintering adults. Second, before the emergence of overwintering adults, spraying pesticides is effective. Suitable options include 20% Exfoliating Emulsion diluted at 1500–2000 times, 50% Anti-Inferior Ultra-Wettable Powder at 2000 times, or 47% Le Siben at 1500 times. These should be applied once every 7–10 days for 2–3 consecutive rounds.
Additionally, applying these agents during the egg-hatching period in nurseries and non-shooting areas helps target younger, more vulnerable insect stages, reducing adult populations effectively. Monitoring the egg-hatching period and the peak larval infestation stage is critical, which typically begins in early August. This is a key time for intervention. To ensure safe harvesting, pesticide use should be stopped about 10 days before asparagus is harvested. Implementing these measures can significantly reduce infestations and protect crop quality.
Thermometer
China Thermometer Supplier
This Infrared thermometer includes sensing head, indicating lamp, display screen, settings, memory, ON/OFF and battery cover.
As a high-quality product with infrared technology mainly designed for human`s body temperature, 32.0℃~ 43.0℃ (89.6℉~ 109.4℉), this
infrared thermometer can ensure the accuracy of measurement through self-checking when it turns on.
For this
infrared thermometer, there are two measurement methods, (1) Sensing measurement:
The infrared thermometer will automatically measure the temperature when the sensing head senses the objective at 1CM; During the sensing process, it is not necessary to contact the objective; (2) Manual measurement: When the infrared thermometer turns on, press the [ON/OFF" key, push forward the key and then target at the objective at 1CM with the sensing head. the measurement can be completed within several seconds. During the sensing process, it is not necessary to contact the objective.
Note: For both methods mentioned above, a second measurement can be conducted through pressing the [ON/OFF" if the infrared thermometer will not be moved after the first measurement.
