(Informative appendix)

Table A.1 Main diseases of oil peony and their control methods

Name occurrence time hazard symptoms prevention method Gray mold Botrytis paeoniae Spring and June to July Brown water-stained spots appear at the base of seedlings, Gradually wither and fall. Produced after leaf infection Brown, purple-brown water-stained spots, sometimes with no Regular ring pattern, with more leaf tips and leaf margins. disease the gray mold layer is a prominent feature of the disease point. Gray mold is a fungal disease.

Find and clear the affected area in time; 1% Equivalent Bordeaux solution, 65% zinc 500 times solution or 50% ammonium chloride nitrate 1,000 times solution Spray every 10 to 15 days, continuous spray 2 to 3 times.

Brown spot

Cercospora

variicolor

High temperature

Rainy season

Pale white spots of different sizes on the leaf surface Dots, generally a circle with a diameter of 3 to 7 mm spot. The central part of the lesion gradually turns brown, scattered frontally Very fine black spots, with several layers of concentric wheel patterns.

Irregular large size when adjacent lesions merge Lesions. When severe, the entire leaf surface becomes Diseased and dead.

Completely remove the diseased plants and fallen leaves after harvesting, Burned centrally; 600 to 800 before onset Times the prevention of chlorothalonil. Prochloraz EC 600 ~ 800 times solution or 80% carbendazim 800 Double liquid spraying.

Round spot

Pseudocercospora

variicola

The leaves were most affected from August to September. Light on the early leaves Small yellow dots that gradually grow round or near Round lesions, brown and visible Wheel pattern, with many tiny mold spots scattered on it, the center of the lesion is the most dense. Leaf margins and main veins the nearby lesions are mostly semicircular. Severe illness the leaves are scorched.

Spray 3 ° Be stone sulfur mixture in early spring, or 50% Carbendazim 600 times solution. Thoroughly cleared in autumn Sick body. 1% Lime Isometric Bordeaux Liquid, or 800% solution of 50% bacteriostatic, or 65% Daisen Zinc 500 times solution, after onset Spray once every 10 ~ 15 days, spray continuously 1 ~ 2 month.

anthrax

Colletotrichum sp.

High temperature

Rain, dew

season

Harm to leaves, petioles and neck. After flowering in leaves Small brown spots appear on the surface and gradually expand, the inhibitory bacteria of the veins are semi-mild, black Spray 3 ° Be stone sulfur mixture in early spring, or 50% Carbendazim 600 times solution. Thoroughly cleared in autumn Sick body.

Brown, turned white in the middle of the late lesion, Reddish-brown edges, cracked, perforated, spotted Many black spots are scattered, and in humid conditions, Visible reddish brown myxospores, stems and petioles Slightly concave, fungi-shaped strips also appear Spotted, diseased stems often twisted, if tender stems develop Will die soon. Bud scales and petals often suffer Will cause young shoots to wither and deformed flowers.

Spray 70% anthracnose 500 times in the early stage of onset Liquid, or 1% lime equivalent Bordeaux liquid, 65% Daisen Zinc 500 times solution, 10-15 days Spray once and spray continuously for 1 to 2 months.

Root rot

Fusarium solani

Field water

And wet

Environment, heavy

Symptoms can appear after the leaves of spring peony and paeonia show Now. The above-ground part is weak and the leaves are green, Yellow and reddish, with severe branches and leaves withered Dead, if not prevented in time, the whole plant will die Perish. When excavating diseased plants, all roots are often visible or partly rotted to dark brown and visible Traces of eating.

Strengthen confrontation control, turn over soil in autumn Before, apply 1 to 3 Zidan Granules per acre kg, when plowing into the soil, planting holes Also apply 3 to 5 g of the same medicine.

Attention during emergence of adult and adult emergence Control of adults.

Wettable methyl tobzine 600-800 times liquid and 1,000 times octane After soaking in phosphorus mixture for 2 ~ 3 min Row planting.

Fusarium wilt

Phytophthota

cactorum

Grey-green, oil-soaked spots initially appear in spring stem damage Dots, then dark brown to black Into a few centimeters of dark spots. Lesion edge color gradually Shallow, no obvious difference between the lesion and normal tissue limit.

Prevent flooding of stem base. Early onset Spraying Luheng No. 2 Wettable Powder 800 Liquid, 72% DuPont Kerou 600 times, 64% anti-toxic alum wettable powder 500 times Liquid, 25% metalaxyl wettable powder.200 Times liquid.

Stem rot

Sclerotinia sp.

From July to August, water-stained brown rot occurs at the base of the stem.

Then the plants withered off-white. Germ-infected Stems with white mycelia and large black fungi nuclear. Stem rot rarely infects upper branches.

Remove diseased plants in time; soil in severe cases disinfection. Pay attention to drainage during the rainy season. Onset Spray with 70% methyl tobzine or 50% benzene Laite 1 000 times solution for prevention and treatment.

White silk disease

Sclerotium rolfsii

When it occurs from March to early May, the epidermis of the diseased part becomes brown, gradually Develops around and produces white silk in the diseased area Filamentous hyphae Extend to the nearby soil surface, later in the disease base Canola on the surface of the skin or on the surface of the mycelium Seed-like tea brown sclerotia. After the onset of seedlings, Cortex of stem base and root rot, plant water Nutrient and nutrient transport is blocked and leaves turn yellow Wither, the whole plant dies.

Can be poured with 1% copper sulfate solution in the early stage of onset Irrigate the roots of diseased plants or use 25% rust Wet powder 1 000 times solution for prevention and treatment, Watering the roots of diseased plants; 20% methyl can also be used 1000mg of liquid Treatment, spray once every 10 days. After the onset, Use a knife to thoroughly scrape the root and neck lesions, and 50 times liquid with antibacterial agent 401 or 1% sulfur Acid disinfection of wounds and application of Bordeaux slurry Wait for the protective agent, and then cover the new soil.

Rust

Cronratium

flaccidium

Yellow-brown granular summer spores on the back of April to August leaves Pile, yellow-brown spores are scattered after the epidermis ruptures, Feeling rusty with hands, the leaf surface is round at the end or round-like irregular gray-brown lesions.

Dark brown bristle-like winter spores growing on the back of the leaf Seed piles, the whole plant died in severe cases.

Burn out diseased plants intensively; 3 ° ~ 4 ° Be stone sulfur Agent or 400% solution of 97% sodium dirust, 10 days 1 Times, 2 to 3 times.

Grub

Holotrichia

diomphalia

Year-round to grow

Severe season

The leaves are withering and gradually deciduous until full Strains died.

48% Lesbon Emulsion 1000 times liquid or 25% Guangzhi Emulsion 600 ~ 800 times liquid or.200 times liquid of chlordane powder Watering the roots, trapped with poison bait, 5% Zidan particles the agent is sprayed into the soil.

Chinese Saw Flower Day Apatophysis sinica Severely hatchling larvae in the growing season first bite young rhizomes Peel, rotten from the wound near the ground Invade everywhere, and attack the lower part of the root.

Growth and development of ring plants, reducing peony the quality, when severe, causes the plant to die.

Cultivation during this period of pupalization and destruction of soil the room was destroyed. Watering 50% phoxim during the egg hatching period Emulsion or 48% Lesbon Emulsion 1 300 times liquid.
