become a thing of the past. of ♪♪ growers culled the disease citrus greening. it leaves the fruit half green and misshape enanden and sour. it was first detected in 2005 and it's been plaguing citrus growers every ever since. a tiny insect feeds on the leaves. it was not until 1971 that researchers confirmed that it was a bacteria that thrives in the gut of the bug that causes the disease. when he feeds on the tissue or the growth he transmitts transmitts the bacteria from there. it's trouble. travis murphy is it the

president of river country citrus. >> we have already picked these trees once look at the fruit left you can see a lot of wasted energy because these fruits won't make it to the market. travis told me that 100% of his groves are now infectedded infected. is this something that worries you daily? >> daily and at night. there is probably a spot in my bed where it's worn pret tidty worn pretd of. >> so far there is no cure calvin arnold heads up a team raising toracing to find one before it's too late. >> a grower told me today you

have to give me more tools in my tool box. >> in the follow tool box they have strategies from for treatment to already diseased freeze. a plant pathologist is looking to erad canadian eradicate the deadly bacteria from the tries. it could be five years. >> juan has been working on a treatment called they are thermal therapy. they crank up the heat for three to seven days. >> this is three months after the heat treatment and you auld you seeyou -- all you see is the healthy plants. >> they are essentially cured from the disease. cured in a controlled situation. >> juan and his team have a field solution.

>> whatwhat is this? techbility tent trying to acheechachieve. we can increase the temperature inside up to 100. >> how effective is this treatment? we know after the treatment the bacteria significancely significantly reduced. >> the results are good enough that some growers are fashion beingingtheir own tent. his colleague entomologist wayne hunter is tackling it from the other side. >> colonelly currently they spray insoacketinsetted insecticides. and normally you would release a bug that would hunt the problem. hunter has a sleus that solution that is

designed to stop some of the functions. >> we apply the rna to the tree and the insect feeds on the tree and it takes it into it's body. and then they think it's an intruder and it ends up killing it itself. >> a small amount of liquid. >> okay. and that then we are going to threatenthen put our tree. and we'll add our insects to this lyle little try and a cage and we cap this and a nice little cage. and we can leuld actually look at mortality. they are really small. >> they are very small. >> you can see some on the leaves if you look carefully. the body sticks up when they are feeding. >> there is one moving down the leaf. >> we see the first mortality in day three.

you have about 80% mortality by day favour eight. five or eight. and at the end wield have oachbilityd end we'll have 9 90% mortality. >> can you eat it? >> you can break it down with the acids in your stomach. >> he hopes his research will lead to a commercial available spray. even if it's good the path to regulatory approval is murky. >> this technology is so new we don't have regular regulatory outline on how it has to be screened. >> in the meantime citrus growers like traf ises travis murray murphy is taking it one day at a time.

terrorism strategy. therethere is another longterm strategy with the transgenic approach. they are using genes from spinach and putting them florida the citrus treats and the gene produces a protein that inhibits the bacteria. >> a genetically modified organism. a transgenic gene from one organism. >> that is really interesting. >> coming up next we'll we'll be going down to neensz new orleans and we are going to be eating something with six legs we want to hear what you think p of these stories.
