i started 10 plants a few months ago with the intention of experimenting on them as a learning experience. i figured if i could cause a particular problem on purpose, then i would know what to do if that same problem occured by accident. right now, most of the 10 plants have an ailment of some kind that i caused. if you go to my diary you`ll see pics of the different leaf disorders. see how many you can identify from the pics. all these problems are problems that can occur naturally in the patch. none are insect or pest related. none are herbicide related. no human or animal physical damage either. no diseases either (known). the person with the most correct answers gets 25 seeds from my first 1500lber.

Don't have a clue booth but those leaves that brown up and die happen to me often. I thought it was improper spraying technique. applying insecticide/fungicide at wrong strenth causing leaf burn. The over flowering problem probably to much P as in bloom buster 10-60-10....leaf yellowing is a defiency could be iron, although don't know how you could simulate that so will go with not enough K....heavy wilting at all hours maybe overwatering and drowning the roots?? My guesses! LOL

Make a search for "mosaic" above and find some pics and discussions about that virus here on BP. Maybe that´s your problem? Problems with applying too much insecticide might cause similar effects. To be sure make a DNA test for WMV.

This is just a guess, but the leaves look a lot like mine did last year. I took sample leaves to the local coop and they did not find insects or disease. They guessed ozone damage. Later I found serious root rot. If you have poor drainage and water a lot, maybe this is your problem. Just a quess.

I had a hard time believing the Ozone damage thing also. That's why I kept looking for another reason I was having the problems that I had.

we get ozone alerts occationally in the Salt Lake metro area...
it's essentially the same thing as a pollution alert. a warning for people who might have breathing difficulties not to go outside. I've heard of it in other big cities too.
we get to much of if in the big cities, it settles in and stays put ... yet somehow all those other harmfull to the ozone gasses make there way up to the upper atomsphere and then travel from North America and Europe all the way to Antarctica where the ozone hole is. Where it make things worse. ... and that's what i learnt in college almost 20 years ago.

Booth is your garden where a Orange grove use to be. I was thinking just maybe some of the problems just may be from old residue from weed killers that use to be used in orange groves soil from the past. You sure have alot of different things happening there, Just a thought. Greg

I see from above it wasn,t from herbicide that you might have applied. But i still thing it could be some residues from past that are still in the soil

Alex & Steely.. man you`re good! my entire patch was very low in P and K and iron before i planted this year. so in some of the patch i added plenty of everything. in other parts i just added some, or none of whatever it was lacking in so i could see first hand what deficient plants looked like. some of the pics show the effects of no P. some no K. some both.some no iron. some all 3. the flowering problem, you missed. it was 10-50-10. LOL. yep, one wilted plant is from way over-watering, causing root rot. the other is from a very tiny root system.(no P&K). as for the wrinkled up, deformed, skinny plant with long stems, the soil was very lacking in just about everything but N. it had plenty of N. so i gave it 10lbs of ammonium sulfate in a 5` circle just to see what it would do. cont.

causes cont. #1 392.5 Frantz not part of experiment. #2 no P-K no roots, small system t #3-4 excess h2o, continuous watering. #5-6-7-8-9 no P #10 excessive N, no P,K,iron,trace elements. WAY too much N #11-12-13 no K #14 no P, no iron #15 no K, no iron #16 low N, no iron #17 low N-P iron #18 started with good everything levels, stopped P&K foliar feeding 2 weeks ago.(new growth deformed since stopped). #19 392.5 don`t know what ails this one. (yet) # 20 Clark 200 too much 10-50-10. #21 test showed low P so probably over-ferted with 10-50-10 #22 applied 10 lbs aluminum sulfate to 20 sq. foot area already high in N, very low everything else. #23 no P&K, constant flooding-standing water. these are just my findings from my own tests, the results can be interperated by others differently. match the pics and the symptoms to reach your own conclusions.
