spinosad

Where can i buy spinosad in thailand? I need it against citrus leafminer....

[drtreelove]

I have not seen spinosad in Thailand, but if I were looking for it, if not found on Lazada, I would call Khun Vipaporn, the English speaking owner at Limsakdakul Chemikasate, big ag chemi importer and distributor in Chiang Mai. If she is not available, her Thai speaking sales people will be able to tell you if they carry it, and if they will ship to you. 

 

There is a spinosad product that I found online called Success, from Dow Agrosciences, which appears to be registered in Thailand. 

 

I have not used spinosad products because I find them on the more expensive side of biopesticide costs, and I have other more affordable favorites.  But it is an interesting insecticide. It would be appropriate for citrus leaf miner, because of the translaminar property, ability to penetrate leaf surface and get to the larvae where they are feeding between the upper and lower leaf surfaces. But with the waxy cuticle of citrus leaves, you would need to add an adjuvant, a penetrating surfactant for best results. Spray the lower leaf surface for stomata entry as best possible. 

 

Citrus leaf miner is not usually a killer pest, but it can cause severe disfigurement of the young leaves. I would assess the level of damage and determine if control is really necessary. I would also avoid heavy pruning and high Nitrogen chemical fertilizer, both of which can stimulate excessive new vegetative growth where the leaf miner moths prefer to lay eggs and the larvae feed. 

 

Thanks or posting this inquiry, it reminded me that I wanted to read up more on spinosad. Sorry I don't have the answer you are looking for. 

 

If you can't find spinosad, consider abamectin (not organic program compatible) a very effective translaminar. Imidacloprid is widely used for CLM. It's a slow moving systemic for root uptake, but has a long, full season effectiveness. Or an organic program compatible approach could be horticultural oil to smother eggs if you get the timing right and do repeated sprays through the growing season).  My favorite preventive is 70% neem oil every two weeks, but that also is hard to find in Thailand. YOu could add an azadirachtin neem concentrate as a repellent and reproductive disruptor for the moths along with a summer hort oil.

Looking for some fertilizer components on lazada and found this.

https://www.lazada.co.th/products/15-ml-i555716515-s1016650547.html?spm=a2o4m.searchlistcategory.list.10.16be5d0649eMgT&search=1

It says spinosyn on the package when you zoom in but maybe the syn is for synthetic ?

You have a good eye.  That's it, a spinosad equivalent.. 

 

"Spinetoram is a fermentation product of Saccharopolyspora spinosa and is an analogue of the insecticide spinosad (PC code 110003; registered for application to numerous crops). Spinetoram and spinosad are considered toxicologically equivalent. Its mode of action is disruption of nicotinic/gamma amino butyric acid (GABA)-gated chloride channels."

 

 "The use of emulsified crop oils or methylated crop oil plus organosilicone combination products as spray adjuvants are recommended.  For resistance management purposes, the use of the same ingredient or products with the same mode of action on consecutive generations of insects should be avoided. "

I think i will get some next lazada order now that you have explained it. Im not much on the scientific stuff so good to have someone on here that understands it.

I didn't write the scientific stuff, I searched it out because the new generation of reduced risk bio-pesticides interests me, I work with plant problem diagnosis and treatment everyday and I learn something every time I follow up on a question like this.  

 

What is even more interesting than acquiring an arsenal of pest control products, is building "high brix", "high nutrient density" biologically active soil, resulting in real plant health.  Then your plants will acquire natural resistance to pests and disease and you won't need the chemistries.

Well keep on searching then, your posts are whats needed to help bring about some change here.

I was thinking just the same thing. Without Drtreelove where would we get our info?

Dr T. is as close as we get to an agronomist on the forum. I often wonder how anyone in senior management in Bayer would get some sleep after buying the original Agent Orange "trustworthy" manufacturer liability?

Let me add to that. I think I have been using roundup for over thirty years, and still have done this year. Yes, we need more professional help

I dont farm rice but wondering about availability here along with cost/coverage comparison versus glyphosate. I see it is popular in many other rice producing countries.

It's not compared with glyphosate as it is used post emergence.

I just put the website up because sometimes if you cannot get hold of an agronomist,having a list of herbicides,fungicides and insecticides is handy to be able to see what chemical formulation is used for the product and your local shop may have something similar in Thai but with the formulation still written in english on the product.

Here is the Bayer website for thailand for available products.
