Citrus has entered the coloring period, what kind of medicine is used to control red spiders?

Pay attention to the prevention and control of red spiders during the coloring period

Citrus late-maturing varieties enter the coloring period, and after the peel is colored by red spider damage, the peel cannot be restored, and the coloring will be affected.

When the skin is still green from the young fruit to the expansion stage of the fruit, the red spider is not serious, the peel can be gradually restored in growth, and there is no way to recover the color, and it is necessary to do a good job in prevention and control.

Medication for the control of red spiders during the coloring period

At this time to prevent and control red spiders, the choice of drugs should consider safety, the effect of low temperature weather, whether there is an impact on the color, etc.

For example, mineral oil is not recommended to be used during the coloring period, because the weather is not suitable for drought and is easy to affect the greening of the fruit.

For example, alkyne mite is not recommended to be used during the coloring period, because the effect of low temperature weather is affected (unless other red spider drugs are compounded), and the emulsion agent coloring period is not easy to mix with other agents.

For example, fludylamine is not recommended to be used during the coloring period, because the effect of controlling red spiders in low temperature weather is affected, the effect of high temperature weather is good, and the effect of low temperature is mainly on sterilization.

For example, spironyl ester is not recommended to be used during the coloring period, because the effect of low temperature weather is affected, and the effect of high temperature weather in summer and autumn is good.

For example, additives are not recommended to be used during the coloring period, mainly considering safety issues.

The above is purely a personal point of view, it is relatively conservative, because everyone has worked hard for more than half a year, there is no need to risk medication, there is a problem that cannot be remedied, and it is possible to lose everything.

The remaining commonly used citrus red spider agents include acetazole, biphenylhydrazine ester, acetazole nitrile, avermectin and the like.
