As for the mildly diseased leaves, cut off the lesions together with part of the healthy tissue, then spray Bordeaux mixture for protection. Of course, there are many other liquid medicines to choose from, such as 80% zineb wettable powder at 500 times dilution or 25% metalaxyl wettable powder at 500-800 times dilution, etc. Rotating the medicines gives better results.

2. Control methods
Promptly remove diseased leaves and destroy them in a centralized way to reduce the source of disease; start spraying from the early stage of the disease to prevent it from spreading, with liquid medicines such as 65% zineb at 500 times dilution or 25% myclobutanil emulsifiable concentrate at 800 times dilution; spraying 1-2 times every 10-15 days can be effective.
Overall, the cultivation method for the fiddle-leaf fig is not difficult, and it has strong adaptability; as long as everyone takes a little care in maintaining it, it will not suffer from pests and diseases.

What medicine to use for grape bitter rot?
Bitter rot mainly harms the fruit, with the damage being more severe on nearly ripe fruit. High temperature, abundant rain, and humidity are the main factors inducing more severe occurrence of bitter rot, so what medicine to use for grape bitter rot?
What medicine to use for grape bitter rot?
(1) Do a good job of orchard sanitation and eliminate the overwintering source of the pathogen
After leaf fall or before taking the vines down from the trellis, thoroughly remove the diseased mummified fruit on and under the trellis, take them outside the orchard in a centralized way and destroy them, treat the places where the pathogen overwinters, and reduce the amount of overwintering inoculum. After the grapevines are put up on the trellis or before bud break, spray the whole orchard once with 30% Longdeng Fulian (tebuconazole·carbendazim) suspension concentrate at 300-400 times dilution, 60% Tongjia (copper calcium·carbendazim) wettable powder at 300-400 times dilution, or 77% Duoning (copper calcium sulfate) wettable powder at 300-400 times dilution, to kill the latent pathogens on the canes.
(2) Spray medicine at the right time during the growing season
Bitter rot mostly occurs sporadically, and generally orchards do not need separate spraying for its control. In the few orchards that had heavier disease in previous years, start spraying 1.5 months before grape harvest or when diseased clusters are first seen, once every 10-15 days, and about 2 consecutive sprays can effectively control the occurrence and damage of this disease. The commonly used effective medicines are the same as the effective medicines for controlling "black rot."
