Effects of nematicides, lime, and herbicide on peach tree short life in georgia.
نویسندگان
چکیده
Peach tree mortality was 75% five years after planting on a site associated with peach tree short life and receiving no nematicide treatment, no lime, and with cultivation for weed control. Mortality was reduced to 29% by preplanting plus postplanting applications of DBCP (1,2-dibromo-3-chloropropane) and with herbicidal weed control. Preplanting applications of nematicides alone did not effectively reduce tree mortality or increase yield. Lime applications increased yield but did not affect tree growth or survival. Survival was higher with weed control by a herbicide than with control by disk cultivation. Populations of Macroposthonia xenoplax were correlated positively with tree mortality and negatively with yield. The other nematode consistently present at the site, Tylenchorhynchus claytoni, was not associated with either tree mortality or yield.

Annual postplanting applications of 40.7 kg/ha DBCP (1,2-dibromo-3-chloropropane) controlled Macroposthonia xenoplax (Raski, 1952) deGrisse and Loof, 1965 in peach tree short life sites, reduced bacterial canker incidence from 74% to 6%, and inreased the average life of the trees from 3.9 to 6.8 yr for a 7-yr test period. Hydrated lime at 5.5 kg per planting site reduced bacterial canker incide...

متن کاملEffect of Pre-Harvest Salicylic Acid and Iron Treatments on Postharvest Quality of Peach Fruits
Peach is a highly corrosive fruit with a short shelf life (less than 7 days at room temperature)susceptible to diseases, pathogens and physical damage. The storage or marketable life ofhorticultural crops can be extended by various treatments applied to them after and/or beforeharvesting. Fruits are usually treated with a range of materials [(e.g. salicylic acid (SA)] to...
