In the past few days, farmers have sent photos of their own peach orchards, and there are many small white spots on the branches of peach trees, and they don't know what it is. After our identification, we found that this is a pest, called peach tree mulberry white borer, which is a more common pest in the peach tree planting process.
Mulberry white borer is more harmful to peach trees, when the occurrence is serious, female adults and nymphs live in groups on the branches to suck sap, resulting in tree weakness, if not timely control, even cause direct death of peach trees. So how to control peach tree mulberry white borer? Below I give some advice.
First of all, for the mulberry white borer that appears in this period, because the fruit has been harvested, most of the leaves have fallen, and it can be combined with pruning to directly scrape the more concentrated mulberry white hopper community.
Secondly, for pharmaceutical prevention and treatment, I recommend several formulas with a long duration of validity, which you can use as a reference.
10% high potency cypermethrin. Pyridyl ether suspension 750 times + silicone
30% spironoid ethyl ester. Pyridoxine 1500 times + 20% acetamidine 1500 times + vegetable oil
22.4% spironoid ethyl ester 2000 times + 70% acetamidine 1500 times / 25% thiamethoxazine 1000 times + silicone
20% methylphenidate. Pyridine 1500 times + 10% homeopathic cypermethrin 1500 times / 20% enprimethamine 1500 times + additive
33% spironoid ethyl ester. 2500-fold thiazide + acetamiprid / thiamethoxamine / high efficiency cypermethrin and other + additives
45% chlorpyrifos 1000 times + high efficiency cypermethrin + additive
In the past, the control of ticks was mostly used to kill phosphorus, but this ingredient has been banned. And the above formulas are practiced, the current effect is relatively good!
After the prohibition of phosphorus killing, the main active ingredients of the control of ticks, pyrithione, thiazidone, ethyl spironium, etc. From the perspective of effect, pyraprofen, thiazide, spironoid ethyl ester, quick-acting slow, but long-lasting. Therefore, when selecting a preparation, it is often necessary to choose to use a variety of ingredients of the compound ingredient, and then with nicotine or permethrin insecticide to improve the quick potency.
Finally, it should be reminded that auxiliaries such as silicones are indispensable agents for the control of scale insects, because there is a thick waxy layer on the outside of the insects, and the use of osmotic agents can make the effect of the drug better.
These are my suggestions, hoping to help growers facing the harm of ticks!
