First, powdery mildew
1. Symptoms: Symptoms occur mainly on the leaves. The seedling stage and the adult stage are all onset. White, near-circular, small-powder lesions appear on the foliage, and the entire leaf is covered with white powder.
2. Incidence conditions: The bacteria survived on the diseased body and spread by airflow. Severe onset of high temperature and high humidity.
3. Control methods: 1 pay attention to ventilation and wet, prevent condensation. 2 chemical control, available 20% Triadimefon EC 2000 times, 50% polysulfide suspension 400 times, 50% sulfur suspension 200 times, sprayed every 5-7 days, even spray 2-3 times.
Second, gray mold
1. Symptoms: Major hazards to flowers and fruits. The peduncles of flowers and young fruit were initially immersed in water, soft rot and dense gray mold.
2. Incidence conditions: The pathogen survives with the diseased body, and it can also be wintered in the soil with sclerotia. Low temperature and high humidity are the onset conditions.
3. Control methods: In the initial stage of disease, 50% fast keratin is used for 1500 times, 50% for kaidai is 1000 times, 50% for Nongliling 500 times, 65% for metalaxyl for 1000 times, and 50% for more than 50%. Double fluid, 40% Trickle 800 times, spray once every 5-7 days, spray 2-3 times. Rainy days can be used 20% fast Ke Ling smoke agent or 10% quickening dust. In combination with 2,4-D dip to add 0.4% amount of safranine or polymyxin, both falling and disease prevention.
Third, cotton rot
1. Symptoms: The main hazard to the fruit, in the early fruit oval-shaped water-immersed dark green lesions, slightly sunken, subcutaneous pulp brown rot, surface layer of white mold. Sometimes it also harms the stems and leaves. It appears as dark green lesions on the petiole and stems. It is rotted like a boiled water when it is wet.
2. Incidence conditions: The pathogens in winter in the soil, spread with water. Low temperature and high humidity are favorable for the disease.
3. Control methods: 1 Soil treatment with B-Fe-Al-Mn-Zn, according to 10 grams per square meter of medication, add appropriate amount of fine soil and mix well, spread in the seedbed or planting hole. 2 Chemicals can be used to control 70% mancozeb 500 times, 80% acetophosphate 500 times, 58% trebic Mn 500 times, 50% trepriose 500 times, 50% DT 500 times, 7- Spray 10 times a day, spray 2-3 times.
Fourth, brown spot
1. Symptoms: Symptoms mainly occur on the leaf blade, and the disease occurs from the bottom to the top. The lesion is round, with a yellowish-white middle and a brownish-brown edge. Foliar lesions slightly elevated, rough surface, water-backed leaves, chlorotic halos.
2. Incidence conditions: The germs survived on the seeds or on the sick bodies and spread with air currents and watering. Diseases are endemic due to high temperature and humidity.
3. Control methods: 1 Seed disinfection treatment: Soaking with warm water at 55°C for 15 minutes, strengthen the ventilation and disperse moisture. 2 chemical control: 75% chlorothalonil 600 times, 50% acetaminophen 1000 times, 50% times times 500 times, spray every 7 days, even spray 2-3 times, rainy days available 40% Chlorothalonic smoke agent or 5% chlorothalonil dust agent.
V. Mosaic virus disease
1. Symptoms: dark green spots on the top leaves, chicken claws on some of the leaves, and nodules on the surface of the melons.
2. Incidence conditions: The pathogen of this disease is a plant virus, which is transmitted by locusts, and the seeds are transmitted through manual contact with humans. High temperature, drought, strong sunlight, and weight-related deficiency.
3. Control methods: 1 whole shed disinfection treatment: Before the harvest, before sowing, with 5% bacteria clear 300 times solution, plus trisodium phosphate 500 times liquid, the whole shed spray. 2 timely control of locusts, cure lice and disease prevention. 3 Pharmacy control: At the beginning of the disease, 5% of the bacteriocin was used to clear 300 times of the liquid, 1.50% of the diseased lingzhi was 500 times liquid, and Lvfenwei No. 1 was 600 times liquid, once every 10 days, and sprayed 2-3 times.
