Because I love lemons and the fragrance from the flowers, something of the first I did when I moved from Norway to Thailand was buying a small lemon tree. Already then, I saw something was wrong with the leaves, see picture: http://picasaweb.google.com/dagoft/LemontreeNonthaburi?authkey=Gv1sRgCL6tloux-LWndQ&feat=directlink I try to consult the local dealer that gave me: diethyl (dimethoxyphosphinothioylthio succinate 57% W/V EC, smells bad - or dangerous, and did not solve the problem. The insects/parasites eat or make the fruitstands disappear shortly after blooming. I spray the tree (leaves and stem with water frequently. Now I hope the joint wisdom of this forum can help saving the tree. Thank you so much in advance. Best regards, daof Nonthaburi, Thailand
