Citrus greening continues to spread in citrus growing areas
...alifornia, researchers are continually looking for evidence of the citrus psyllid. If it is found there, citrus trees will need to be closely monitored for disease symptoms. Citrus greening can only be managed, not completely controlled. By reducing the psyllid population through the use of insecticides, t...Study shows cane sugar, corn sweeteners have similar effects on appetite
