Gardenia leaf-spot mainly infected the middle and lower leaves of Gardenia jasminoides Ellis making the leaves blotchy and withered.The disease occurred from March to November and became serious when the temperature was over 25 ℃.The pathogen(Phyllosticta gardenicola Saw.,P.gardeniae Tassi)overwintered as conidiocarp or hyphostroma on the infected leaves.The result of the test showed that the control effect was over 90% when 50% Carbendazim WP(diluted 1 000 times)and 30% LDN flowable formulation(diluted 2 500 times)were sprayed three times.
