How to prevent and control jujube rust
Jujube rust is the main parasitic disease, and the jujube gardens with many surrounding cypress crops are seriously affected. The rain is frequent and the humidity is high. In terms of prevention and control, fruit growers should pay attention to reasonable close-graining, trimmed over-closed branches to facilitate the ventilation of airy trees. In the rainy season, attention should be paid to timely drainage to prevent the orchards from getting too wet, and vegetables and other regularly irrigated crops cannot be planted between the rows. Clean the fallen leaves in the jujube garden, concentrate burned or buried deeply, and eliminate the source of the initial infection. Prior to the germination of the summer spores, spray 80% Mancozeb WP 800-1000 times. In the peak period of rust, spray 12.5% ​​diniconazole WP 3000 times solution or 20% difenomethyl hydrazine dispersible granules 5000-6000 times solution or 25% tebuconazole water emulsion 4000 times solution + 30% EC 3000-4000 times liquid.
