The main growth regulator applied in apple trees to increase the harvest period is aminoethoxyvinylglycine (AVG), which is indicated to delay harvesting and avoid fruit drop
, and to improve the maintenance of fruit quality during storage due to reduction in ethylene production (YILDIZ; OZTURK; OSKAN, 2012; BRACKMANN et al., 2014).
There is also stunted growth of the crop, attacked fruits shrivel and there is premature fruit drop
. Mature females lay about 300-600 eggs on various plant parts.
The attacks on fruits often resulted in fruit drop
. Healed lesions on avocados could affect its commercial value, especially that of varieties cultivated for export, because it is considered a defect in fruit quality.
AVOID DURIAN FRUIT DROP
- One of the usual problems in durian in Luzon is that many small fruits drop.

(seen in the above left photo on Norton vines in Missouri) and rachis reddening and berry shrivel (pictured above right on Cabernet Sauvignon in Maryland).
Maximum fruit yield plant-1 (96.7 kg), and fruit drop
(59.3 %) were recorded at pre-bloom stage, whereas maximum single fruit weight (5.6 g), fruit size (5.2 ml), flesh percentage (76.9 %) and minimum fruit stone percentage (23.1 %) were observed when boron was applied at fruit set stage.

, yield and quality in kinnow mandarin.
Also, low pollination, less fruit setting (less than 0.1%), high fruit drop
percentage, unnecessary stresses (injury) and improper management practices during budding or grafting, time of irrigation, pruning and time of application of fertilizers are contributing substantially to the downfall of the industry.
The morphological parameters regarding the tree height (cm) was recorded using measuring tape from the crown level to base of leaf apex, fruit set (%) was recorded by taking the number of fruits divided by numbers of flowers, fruit drop
(%) was recorded by total number of fruits set and number of fruit dropped were counted and calculated and expressed in percent.
Premature bud and fruit drop
is a serious problem in wax apple production and quality.
The parameters under study were Ferment fruit (%), Fruit drop
(%), Benefit ratio (%) over control, Bunch weight (kg) and Cost benefit ratio.
“Employees deeply appreciate when their boss cares enough to provide them a little something extra at work, especially when it's not required,” says Mike Dorosz, owner of Detroit Fruit Drop
, an office fruit delivery subscription service based in Metro Detroit.
