Complete Guide to Pear Bagging Time and Methods, Master the Latest Techniques
In pear cultivation, one important task is bagging. For juicy fruits like pears, bagging is generally done during growth, mainly to prevent piercing-sucking pests from feeding on and damaging the pears, and also to prevent various diseases, as well as birds and animals in the wild from pecking at them. It can also avoid pesticide damage during spraying, protect fruit growth, and ensure quality is not affected. However, bagging has certain requirements: it must be done at the right time, with the right bags, and some preparatory measures are needed before and after bagging. Let's take a look together!
1. Bagging Time
Bagging too early when the fruit is too small makes it easy to knock them off, while bagging too late is ineffective because pests and diseases have already occurred. Therefore, bagging should generally be done after the flowers have completely fallen, the fruit has set securely, and the fruit has grown to the size of a ping-pong ball. At this time, the fruit is firm and free of pests and diseases, making it the best time for bagging. For some varieties prone to rust disease, bagging should be done earlier; for slower-growing varieties, bagging should be done later. Bagging should be done on sunny or cloudy days, not on rainy days.
2. Preparation Before Bagging
Before bagging, spray pesticide once, applying fungicides, bactericides, and insecticides to prevent pests and diseases from occurring on the fruit after bagging. Or if tree diseases spread to the fruit, spray pesticide as well. Half a day to one day after spraying, once the pesticide has dried, then bag. For spraying, it is not suitable to use protective agents; use fast-acting agents instead. If bagging is not done for a long time after spraying or if it rains, spray again.
3. Choosing Bags
When choosing paper bags, select ones made of hard, dense material, preferably tough material. You can test by soaking in water; bags that do not fall apart and remain intact are suitable. Plastic bags should be transparent; it is best not to use black, light-blocking ones, as they affect light reception. You can put a foam net tube bag inside, then put a transparent plastic bag outside to prevent insects from piercing and sucking the fruit.
4. Bagging Method
When bagging, first bag the upper and inner fruits, then the lower and outer fruits. When bagging, open the bag to its maximum opening, then hold the fruit with one hand and hold the bag with the other, put the bag over the fruit, then gather the pleats at the bag opening and tie the bag opening tightly with string or wire. Plastic bags can be tied directly using the excess part.
5. Points to Note
Before bagging, fruit thinning is also needed: thin out diseased fruits and diseased branches, as well as excess fruits. Choose the fruit positions to keep before deciding on bagging. After bagging, generally about one week before the fruit matures and is harvested, open the bag opening for ventilation; paper bags do not need this, and then remove them before harvest.
The above is the process of pear bagging, including preparation work, selection, and specific methods. This is a complete process, provided for everyone's reference. I hope that after reading it, it will be helpful for your own practical operation, and you can also bag reasonably according to your own needs.
