How to prevent and control infectious gummosis in peach trees
It is a disease caused by a fungus of the Ascomycota subphylum. It mainly harms branches and trunks. When it occurs on 1-year-old young shoots, small protrusions first appear centered on the lenticel layer, later forming tumor-like protrusions 1 to 4 mm in diameter, and no gum flows that year. By early April of the following year, the tumor

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.

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.
