Tech Grade: 96%TC

Technical requirements for use:

1. In the peak period of hatching of red spider eggs or the peak period of nymphs, spray with water when there are 3-5 mites per leaf on average, and can be applied again at intervals of 15-20 days depending on the occurrence of pests. Can be used 2 times in a row.

3.On fruit trees, it is mainly used to control hawthorn spider mites and apple pan-claw mites on apples and pear trees; citrus pan-claw mites; also control fruit leaf cicadas, aphids, thrips and other pests

Advantage:

1. Fast mites killing

After the growers sprayed pyridaben, as long as the mites come into contact with the liquid, they will be paralyzed and knocked down within 1 hour, stop crawling, and eventually die from paralysis.

2. High cost performance

Pyridaben has a good acaricidal effect, and compared with other acaricides, such as spirotetramat and spirotetramat, the price is the cheapest, so the cost-effectiveness of pyridaben is really high.

3. Not affected by temperature

In fact, many pharmaceuticals need to pay attention to temperature changes in the use of, and worry that the effect of temperature will not achieve the best effect of the pharmaceutical. However, pyridaben is not affected by temperature changes. When used at high temperature (above 30 degrees) and low temperature (below 22 degrees), there is no difference in the effect of the drug, and it will not affect the efficacy of the drug.

Shortcoming:

1. Short duration

Pyridaben, compared with other acaricides, has a relatively short duration of effect. It is recommended to use it with a long-lasting agent, such as dinotefuran, which can increase the duration of the agent, up to 30 days.

2. Greater resistance

Pyridaben, although it has a good killing effect on mites, has been used more and more, resulting in increasing resistance in recent years. Therefore, if you want to use pyridaben well, you must solve the problem of pyridaben resistance. In fact, this is not difficult, as long as other drugs are compounded, or used alternately with acaricides with other mechanisms of action, do not use pyridaben alone Spirit, can greatly reduce the degree of resistance.
