Post by: dlhvac on October 09, 2019, 02:41:54 PM: You’re welcome millet I could not stand by while my citrus were dying I just sprayed the psyllids today with spinosad. I have recovered four of my trees with the brassinolide and the nano zinc those are only a handful of the articles I’ve read . I chose the ones that were promising and tried them . The problem is that the brassinolide is not approved for commercial citrus , it was discovered in rape plant pollen in 1979 as I found out I have tried the organic brassinolide 14 epinbrassinolide 298.00$ a gram and the synthetic for a great deal cheaper 10.99$ for ten grams with no difference it takes 500 pounds of brassica pollen to make that one gram. The chemically made one is 28 epinbrassinolide no difference. I’ve found tremendous growth in dwarf citrus and standard also in my mango trees and tremendous growth in dragon fruit. I’m just trying to tell people there are alternatives to taking out the trees and burning them I will get a whole lot of lemons Meyer and ponderosa , and blood oranges this year and next I’ll let the Washington naval hold fruit the have grown back enough branches.

Post by: Ilya11 on October 09, 2019, 06:05:29 PM: There is another simple and cheep chemical that is worth to try in combination with your Zn and brassinolide treatments. N-acetylcysteine is being tested to treat Huanglongbin in Brazil and it is rather effective against a related bacteria Xyllela fastidiosa.

Title: Re: Treatment for HLB
Post by: Bomand on October 14, 2019, 06:06:25 PM: Good information. I am in favor of any/all help to find a soloution to the hlb situation. I am unsure that this treatment will be affordable to the home citrus grower. Perhaps the things that will work for the commercial growers will flow downhill to the backyard grower. Or.....will the only folks that can afford the "cure" be commercial growers....will citrus become so expensive that grass roots folks can not buy it? Lots of questions still to be answered....if they find a stop.

Post by: dlhvac on October 14, 2019, 06:15:55 PM: In case anyone like to read here is a list of plant hormones and what they do do not overdose a citrus tree it can cause a severe reaction most are available online experiment with seed grown citrus for example I use gibberellic acid with potassium and phosphorus with no nitrogen. To induce blooming in young citrus that normally take many years to flower I have gotten a pomello to flower and set fruit in its second year. With the process described

Title: Re: Treatment for HLB
Post by: lebmung on February 24, 2020, 07:05:29 PM: I have one thought that can kill HLB.

A systemic copper, a form of copper bound with aminoacids, it goes into the plant and it's an effective bactericide. I use this for mangoes if they show any sign of anthracnose (hardly because all the new scions I treated them already).

I don't have any infected plant, but if someone wants to experiment I can help.
Title: Re: Treatment for HLB
Post by: kevinfolta on February 25, 2020, 07:29:29 AM: Right now there is no demonstrated treatment for HLB. There is a lot of snake oil out there. The only success is in prevention from genetic tolerance in some rootstock and scion varieties, and some GE trees show some promise to live with the infection. There is no cure.

Post by: lebmung on February 25, 2020, 04:29:08 PM: Copper and its alloys are a bactericide. Put water in a copper bowl and it will kill most of the microorganisms.
