Durian Psyllid invasion

[ward]

Hi everyone!

I'm dealing with an issue on my durian trees—Durian Psyllids seem to have taken up residence, and I’m looking for advice on how to get rid of them effectively.

Has anyone had success with specific methods or treatments that can be purchased straight of Lazada? (Currently a little lost in all the available products online, and not sure how badly they will affect also the good fauna.)

 

I'm open to organic options, but I'd also love to hear about any other approaches that work well.

 

Attaching a photo for reference.

 

Thanks in advance for any tips!

Little option other than to spray insecticide for sap suckers as well as treating the ground under to eliminate ants that may be farming them.

Spraying oil to follow up .

Chaindrite Stedfast 30SC. 30 ml of the concentrate per liter of water. The active ingredient is bifenthrin, a potent pyrethroid with residual effectiveness (the pest won't return for awhile). It's a contact insecticide, not systemic, won't penetrate durian fruit. It will get an immediate knock down of the sucking insect pest, and ants. (Don't spray the soil, only the tree trunks and foliar canopy,) Use a 'spreader-sticker' adjuvant. Use PPEs, cover skin, long sleeves, long pants, gloves and mask. Respirator not required.

 

Permethrin, cypermenthrin or other pyrethroids would be similar and just as effective. 

 

Pyrethroids classs of chemical insecticides are based on the chemistry of the naturally occuring extract from a Chrysanthemum flower, called pyrethrum or pyrethrins. Pyrethrins are just as strong for 'knockdown', but biodegrade in 12 to 24 hours (which is why it is considered 'organic program compatible'. ) You can use the organic product, if you can find it, but it will be much more expensive, and it  won't have the residual effectiveness of bifenthrin. 

 

Pyrethroids are relatively low toxicity for mammals, people and pets, but are highly toxic to fish, keep away from ponds and waterways. "Good fauna" will be killed also. But you can work on restoring that with an organic program, after the acute infestation is controlled. 

 

This approach and pyrethroid chemistry is not organic, but then neither is your entire management program or your trees would not have this plant pest. Healthy plants grown on healthy soil don't get pests or diseases. Physiological stress, from poor growing conditions, poor water management, and nutrient deficiencies will make plants susceptible to pests. Soil fertility and good water management will help trees develop natural resistance to pests and disease.  Avoid high NPK, high salt index chemical fertilizer, which creates a pest magnet. 

 

Insecticidal soap, wood vinegar, lemon grass concentrate, rosemary, cloves and other botanicals are organic options, but will require repeat spraying every week until pest infestation is controlled.
