Comprehensive Control Methods for the Peach Borer Moth in Peach Cultivation
The peach borer moth larvae bore into and feed on peach fruit, causing gumming; the fruit discolors and drops, or the interior becomes filled with insect frass, making it unfit to eat, and this has a great impact on both yield and quality. I. Occurrence pattern. In Shandong, this pest occurs in 2-3 generations per year, mainly overwintering as mature larvae in cocoons inside damaged mummified peaches, bark crevices, gaps among loose stones in embankments, chestnut burs, sunflower heads, castor seeds, and corn and sorghum stalks, with a small portion overwintering as pupae. In Shandong, the first moth emergence of the overwintering generation occurs in mid-May, with the peak in early to mid-June; most eggs of the 1st generation are laid on early-maturing peach varieties, with the most eggs laid on the ventral (belly) side; the newly hatched larvae appear in mid-to-late June and mainly damage early-maturing peach fruit, boring into the fruit to feed; mature larvae spin cocoons and pupate at the stem cavity of damaged fruit and in bark crevices. The 1st-generation adults begin emerging in early July, with the peak from late July to early August; adults are highly selective in egg-laying, basically laying eggs on late-maturing peach varieties and pomegranates; newly hatched 2nd-generation larvae are found in mid-to-late July, with the peak in early to mid-August; by late July, larvae are already found maturing and pupating. The pupation peak is in mid-to-late August. As late-maturing peaches begin to be harvested, adults then move to other crops to lay eggs and continue causing damage.

What are the control methods for scale insects on peach trees
There are many species of scale insects that harm peach trees. The main species occurring in our province is the globose scale (Eulecanium kunoense), belonging to the order Homoptera, family Coccidae, genus Eulecanium. When its population is large, the affected branches are covered with dense layers of scale shells, causing poor tree growth; in severe cases, the leaves and small branches wither and die, and even the whole plant may die.

Peach Tree Rot: Control Methods and Key Technical Points
Peach tree rot, also known as dieback disease, causes branches to wither and die after the peach tree is affected, forming canker lesions on large branches and the trunk; if not treated in time, it quickly causes the entire tree to die. The main causes of this disease are: freeze damage and extensive management; improper fertilization and years with heavy autumn rain,

How to prevent and treat jujube witches' broom disease? Essential methods for anyone growing jujube trees
Jujube witches' broom disease is a viral disease caused by mycoplasma-like organisms, transmitted by leafhopper insects such as the round-spotted leafhopper, or through infected root, stem and leaf seedlings or the graft buds and rootstock of grafted seedlings. It is fairly common in affected regions and often becomes the "cancer" of jujube cultivation. At present there are several treatments

What are the propagation methods for jujube saplings? Teach you how to plant them correctly
The jujube tree is an important fruit tree in our country. Its root system is well developed, and some roots close to the ground can produce vigorous root-sucker seedlings. Propagating by dividing root-sucker seedlings is both simple and labor-saving, and is an important method for developing jujube trees. The division propagation of jujube root-sucker seedlings is carried out in the following two steps

What are the control methods for the jujube rust mite?
Jujube trees are generally more common in the north and relatively rare in the south. For friends who grow jujube trees, the thing they fear most is the damage of pests. Once a jujube tree is attacked by pests, not only will the yield decrease, but the fruit produced will be bitten and damaged by insects, and in more serious cases it will

What are the control methods for the peach fruit borer on jujube trees?
Also known as the peach borer moth and peach spotted borer moth, it is an omnivorous pest distributed throughout the country. Its larvae damage the fruits or seeds of many plants such as winter jujube, peach, plum, persimmon, chestnut, apple, pear, pomegranate and hawthorn. When the fruit is damaged, it becomes filled with insect droppings, causing rot, and in severe

What are the control methods for the tortoise wax scale on jujube trees
In recent years, the tortoise wax scale (Ceroplastes japonicus) has spread through the counties of our city, causing serious damage, which has generally weakened the vigor of jujube trees, significantly reduced yields, and even caused total crop failure. In order to effectively carry out chemical control of the tortoise wax scale on jujube, since 1996 we have carried out control trials for 4 consecutive years

Prevention and Control Methods for Bark Cracking and Trunk Dehydration in Young Jujube Trees
Yining County once developed jujube trees on a large scale. In years with heavy winter snowfall, when the snow melted in early spring, the trunk below the snow line (about 20 cm high) was soaked by melting snow water and exposed to wind, causing rot and bark splitting, which blocked the tree's vascular tissue and led to drying and death.
