Microbial Fungal Fertilizer for Controlling Chinese Cabbage Pests and Diseases
Chinese Cabbage is still the largest vegetable planted area. It is necessary not only to adopt correct management measures, but also to apply scientific and reasonable plant protection technology to support high-yield and stable production. Therefore, the prevention and control methods for pests and diseases of Chinese cabbage should be based on prevention, and a combination of agricultural control and biological control should be adopted. If it is necessary to carry out chemical control, do not use high-toxicity and high-residue pesticides to ensure the safety and quality of pollution-free Chinese cabbage. Therefore, regarding the prevention and control of diseases and insect pests in Chinese cabbage production, the following bio-fertilizer expert, Jinbao, will provide farmers with a few solutions to the diseases that commonly occur with Chinese cabbage.
(1) Viral disease: The seedling stage is susceptible to disease (at the moment it is the seedling stage), especially when 7-8 leaves are exposed to continuous high-temperature drought. When the amount of aphids is large, the disease spreads rapidly and the disease is heavy, manifesting as distortion of the mosaic. And shrink, deformed, dwarf, and accompanied by necrotic spots.
Control methods: 1 increase the application of phosphorus and potassium fertilizers, improve the disease resistance of plants, drought watering in time to cool, so as not to induce the disease. 2 Once the disease occurs, use 1.5% of Lingzhi Emulsion 1000 times, spray once every 7-10 days, and spray 2-3 times.
(2) Downy mildew: In the hair-blowing period or during the cooling period, the temperature is very hot and cold, or in case of rainy weather, it is heavy. It mainly infests the leaves, causing blunt, unclear chlorotic spots on the edge of the leaves. . The back of the leaf produces a sparse layer of white mold, and the final leaves turn brownish and dry.
Control methods: 164% antivirus 500 times or 70% mancozeb 500 times alternate spraying, 7 days rotation 1 time. 225% of Rhododendron 800 to 1000 times and 72% of urea manganese zinc WP can be used alternately 800-1000 times per week.
(3) Soft Rot Disease: It is prone to occur in the middle and later stages. The diseased area first starts from the base. The lesions are mostly yellowish watery, and the symptoms are not obvious at the beginning. Afterwards, the leaves fall down during the day, and sooner or later, the uprightness is restored and the disease develops after a few days. Leaves gradually flat on the ground or dehydration dry thin paper-like close to the solid. In severe cases, the roots fester, leaving mucus, and emit bad odor.
Control methods: 1 eliminate pests in time, reduce plant wounds to prevent bacterial invasion. 2 Drain the water immediately after the rain, try to control the humidity in the field, and if necessary, cultivator. 3 The diseased plants were found to be removed promptly and disinfected and sterilized with quicklime powder. 4 chemical control can be used 72% of agricultural streptomycin wettable powder, or neophytin 5000 times, or 77% can be powdered 500 times, continuous control 2-3 times.
(4) Black rot: The diseased plants were mostly "V"-shaped lesions on the leaf margins and gradually expanded inwards. The tissues around the lesions turned yellow and the leaves were dry when heavy. Bad rotten heart, black vascularity of the roots of the vegetable gang. Insects and agricultural activities can spread the disease. High humidity, too much dew, etc. are the conditions that induce this disease.
Control methods: 1 Reasonable irrigation, timely drainage after rain, timely pest control, minimize crop wounds in field agricultural activities. 2 At the beginning of the disease, spraying agricultural streptomycin or neophytin 200ppm, or using 401 antibacterial agent 600 times, or using 50% DT fungicide 700 times, alternating with each other.
(5) Melasma: lesions are round, 2-6 mm in diameter, brown or dark brown, with obvious concentric ring patterns on the surface of the plaque, and black moldy layer on the wet lesion. When the disease is severe, the lesions are connected. One piece, so that the entire blade died. Temperature 13-15 °C, high humidity and rain, dew is too large, sowing too early, lack of fertilizer and water, extensive management, are likely to cause the disease.
Control methods: 1 increase phosphorus and potassium fertilizer, reasonable irrigation, timely drainage after heavy rain. 2 At the beginning of the disease, spray with 75% chlorothalonil or 64% antiviral 500 times. 3 can also be used 50% acetaminophen 1500 times, or 58% metalaxyl manganese zinc 500 times, the above-mentioned several kinds of drugs alternate spraying.
(6) Insect pests: 1 Locust: On the basis of removing the weeds in the headland of the Tanabe, use the anti-influx 2000 times and the imidacloprid 1000 times alternately. 2 Pieris rapae: Use 2.5% of highly effective cyanomethrin (cyanomethrin) emulsifiable concentrate 2000 times or 3000 times of kungfu. 3 Diamondback moth: Resistant to organophosphorus and pyrethroids, it is best not to use it. Can be used 5% Ruijin special suspension 2000 times and 20% diflubenzuron 600 times alternating control.
Introduction:
The bulb of garlic,an allium plant in the lily family.with the pungent flavor and spicy taste.spherical shape with a diameter of 3-6.5cm. The surface is covered with white and papery-skin.
The top is slightly pointed, with residual scape in the middle,many fibrous root marks at the base. After peeling off the skin, a single head or 6 to 16 petal-shaped small bulbs, inserted around the base of the remaining flower stems. The bulbous valve is slightly ovoid, with a membranous outer skin, slightly pointed at the apex, and an arcuate bulge on one side.
In order to ensure the maximum freshness and nutrients.
We adhere to the traditional natural drying method without any human intervention.
