First, it is not suitable to prepare pesticides in living water. Because there are many impurities in living water, it is easy to block the nozzle of the sprayer with its dispensing, and it will also destroy the suspension of the drug solution and cause precipitation.
Second, it is not advisable to increase the amount of water at will. Excessive addition of water will reduce the concentration of pesticides. Spraying on crops leaves only a very small amount of pesticides, which is not enough to kill pests, and some pesticides may even be completely ineffective. Excessive addition of water will also cause the loss of pesticides and lead to environmental pollution. Therefore, when formulating pesticides, we must strictly control the amount of water added according to their use concentration range.
3. It is not advisable to increase the amount of pesticides at will. Before the pesticides are allowed to be produced and sold, they must go through rigorous field efficacy tests, and then determine the actual usage data such as dosage, time and frequency of application. Therefore, the application of pesticides in accordance with the amount specified in the instruction manual can achieve the control effect. Increasing the dosage not only increases the investment, but also causes crop damage, increases pesticide residues in agricultural products, and increases environmental pollution.
4. It is not advisable to spray pesticide crops during the flowering period. The tissues are young, their stress resistance is weak, and they are prone to pesticide damage. Therefore, they must avoid the flowering period when spraying.
Fifth, it is not advisable to spray pesticides before harvesting. The remaining period of high-efficiency and highly toxic pesticides is generally about 60 days, and the remaining period of high-efficiency and low-toxic pesticides is about 15 days. Therefore, it is forbidden to apply pesticides before harvesting vegetables to avoid food poisoning.
6. It is not advisable to spray from top to bottom. When spraying, the spray should be started from the lower leaves of the vegetables, and the spray head should be directed upwards, focusing on the bottom of the blade, and the front of the blade does not need to be sprayed. Because there is usually more medicinal solution falling from the leaves of the plant to the front of the leaf than that of the back of the leaf, only in this way can a good control effect be achieved.

The IOT card of the video surveillance camera needs to be stable enough to keep the flow normal during use without being stopped. After using the IOT network card with defective quality for a period of time, traffic theft or other abnormal conditions suddenly occur, resulting in card suspension, which makes the camera terminal unable to use normally, and may have a significant impact on the business. Generally speaking, video monitoring is event driven or abnormal images (some intelligent algorithms need to be supported) to generate high traffic usage. For example, monitor video playback or live broadcast via 4G/5G remote viewing. Generally, the daily standby traffic consumption is M, and the common definition of video viewing is about hundreds of M an hour.
Currently, for this application scenario, there are also several industry pain points for equipment manufacturers and solution providers:
SIM card adaptation, speed and security issues;
SIM card supply and price stability;
Be unfamiliar with the communication industry and solve the problem of failure;
One point access of multiple vendors.
Honeycomb IoT provides high-speed and stable IoT network cards for security monitoring equipment. Direct connection of operators, including full system, full type and full category IoT SIM cards; Flexible pricing and high cost performance; In addition, it also has a customer oriented efficient management platform, including full lifecycle management and connection management functions.
