How hawthorn red spiders are controlled

1． There are 15 to 20 heads per community overwintering;

2． In early spring, there are 1.5 to 2 overwintering adults per bud;

3． Summer egg ratio 3:1 (or 2 mites per leaf)

Scrape the old warp skin before germination in early spring or tie grass on the main branch before the female mite overwinters in September, remove the set and burn it before the early spring sting; spray 5 degree stone sulfur compound before budding; spray with 0.5 degree stone sulfur compound at the stinging stage and before flowering; spray 0.3 degree stone sulfur compound at the first generation of eggs and incubation; 5000 times avermectin emulsion in summer; 5% nissolan emulsion 2000 times; 15% pyridoxine emulsion 3000 times; peach leaf moth Ground control 50% borax pine 1000 times In late May and mid-to-late August, 1500 times with urea no. 3 was used twice. Pink-necked celestial cow In June to July, adult insects appear in the peak period, artificially captured, sprayed on the trunk with 50% octylthion emulsion 1000 to 1500 times; larval harm, manual digging; tree trunk painted white to prevent adult eggs. Peach brown rot 300 ~ 500 fruits each 1 spot Summer shear, improve ventilation and light transmission conditions; 65% Daisen manganese zinc wettable powder 500 times; 50% carbendazim 1000 times, 75% methyl tolbuzin wettable powder 800 ~ 1000 times; 75% Bacillus Qing wettable powder 800 times. Peach anthrax 300 to 500 spots of young fruits and new shoots Sprayed in late April, mid-May, mid-to-late June and mid-to-late July; 70% methyl tolbucin wettable powder 1000 times; 75% bacillus clear wettable powder 800 times. Peach perforation disease 300~500 new shoots a disease spot spray 3~5 degree stone sulfur compound before germination; spray every 15 to 20 days from leaf spread to fruit harvesting: 65% Daisen manganese zinc wettable powder 500 times; 75% Bacillus Clear wettable powder 800 times; 70% methyl tolbuzin wettable powder 1000 times; 50% hyin wettable powder 1000 times; 1000 times 1000 times the 1000 times polyoxymycin wettable powder; spray 80% Daisen manganese zinc wettable powder 600 times. Peach sore scab disease 300 ~ 500 fruits a disease spot two weeks after the first drug sprayed every 15 days after the first dose: 65% Daisen manganese zinc wettable powder 600 ~ 800 times; 0.5: 1: 1: 100 zinc sulfate lime solution. Appendix C-3 (Appendix to the Standard) Peach Tree Growth and Yield Index B1 Young tree stage (1-4 years): lengthened branch thickness 1.5-2.5 cm; side branch thickness 1.5 cm; 4-year yield per plant 5 kg. B2 Early fruiting period (5-8 years): The average thickness of the elongated head of the main branch is 1.5 cm, the proportion of long and medium fruit branches is 35-40%, the short fruit branches and bouquet-like fruit branches are 60%-65%, and the yield of each plant is 100 kg. B3 Full fruit stage (9-15 years): The main and lateral branches of the extended branches no longer continue to grow, and the head thickness is 1.0 cm; the long and medium fruit branches account for 25-30%, the short fruit branches and bouquet-shaped fruit branches account for 75%; and the yield of each plant is 150 kg. B4 16-18 years at the end of the fruiting period: the annual growth and yield decrease, and the main side branches become long fruit branches or long fruit branches to maintain yield. B5 Aging period (19 years): Aging, significant decrease in production, ready for renewal.
