Non-pollution Control Techniques of Pests in Protected Vegetables

1 Greenhouse Whitefly 1.1 Cultivation "No insects": When you raise the seedlings, do not see "green", ie, weeds and stubbles are completely removed from the shed, and intermediate hosts are reduced. The seedlings and production sheds were separated, and greenhouses were thoroughly sterilized in nursery houses before nursery. The 22% dichlorvos smokers could smoke 400-450 grams per (mu) of greenhouses to eliminate the remaining insects. A nylon yarn pest control net was added to the vents to prevent the invasion of foreign insects. 1.2 Reasonable layout of crops: The plots in and around the plots should avoid mixing cucumbers, tomatoes and beans, and prevent the creation of a good living environment for whiteflies. To promote the first crop of autumn and winter greenhouses to plant celery, rape, garlic and other white wolfberry do not like to eat more low-temperature crops, make whitefly difficult to safely winter. 1.3 Physical control: Using the intense yellowing habit of whitefly, in the early stage of development, the yellow plate (1m 0.2m) was coated with No. 10 engine oil suspended in the rows of greenhouse plants, and the height was even with the plants, every 7-10 Once a day coat of oil, 32 traps per (mu) shed, the effect is good. 1.4 Biological Control: Artificially releasing natural enemies such as Lysimachia sinensis, Chinese grasshopper, and verticillium in the shed, these measures have been successful both at home and abroad, and the results are good. 1.5 Chemical control: Spraying occurs in the early stage and should be carried out in the morning. After spraying the leaves, spray the leaves back. 25% Buprofezin WP 1000-1500x, or 10% Uranus Fragrance 5-20ml/667m2, or 40.7% Lethbone EC 800x, or 25% Chlorhexidine WP 1500 Double liquid, spray control adult or larvae, the effect is good. In addition, 22% of the dichlorvos smoke agent can be used for 0.5 kilograms per mu, and the sheds are closed in the evening and equably ignited into 4-5 points to light one by one, close the doors and windows, and operate as usual in the early morning of the next day. 2 Liriomyza sativae 2.1 Strict quarantine to prevent the spread of spread. 2.2 Agricultural control: Clean the garden, completely remove the insect strains, insects and leaves, and concentrate deep processing; rotate with onion and garlic plants. 2.3 Physical control: Insects are induced by yellow sticks or yellow traps. Sticky insects are replaced in time. Shelter doors and windows are installed to prevent pests from entering the room. 2.4 Chemical control: 1.8% avermectin EC 3000 times, or 1.1% Green Wave No. 2 1000 times, or 40% Green Tea Conserve EC 1000 times, 20% Confero Solvent 2000 times, 48% %Lesborn 800 times emulsion, 75% WP wettable powder 600 times, 20% Lactose microemulsion 1000 times, 5% stuck calcium chlorate 2000 times, alternating spray, once every 4-6 days, Continuous control 4-5 times. The control of adult worms should be used in the morning and the control of larvae should be sprayed at 1-2 years of age. Dichlorvos can also be used to smoke, the method refers to the greenhouse whitefly. 3 Tea sorghum 3.1 Destroy the source of insects: timely eradicate the weeds in the surrounding areas of the greenhouse. After the harvest of vegetables, remove the litter in time and burn them in a concentrated manner. Pay attention to the prevention and control of winter nursery houses and production sheds and eliminate the source of overwintering insects. 3.2 Cultivation of Insect-free Seedlings: Pre-treatment of seedlings is generally 1-2 times. 3.3 Chemical control: The tea plant has a short life cycle and strong fertility. Special attention should be paid to early prevention and treatment. Strengthen the inspection of insects and use them as soon as possible. In particular, the shoots are mainly focused on young shoots, young leaves, and young flowers. Choose 1.8% of avermectin EC 2000~3000 times, or 20% EKG 1000 times, 0.2% BOD (matrine) 300-400 times, or 5% Nisolate EC 2000 Doubling liquid, or 73% of Creutine EC 3000 times solution and 40.7% of Loester EC 1500 times solution, sprayed once every 10 days for 3 times. 4 The control method of red spider is the same as that of the tea plant, but the use of Liuyangmycin to control red spider is most effective. 5 H. armigera and H. assulta combined with field management to eliminate eggs and shed eggs. Tender shoots with eggs were brought out of the shed to be removed. Remove the old leaves at the bottom to increase ventilation and light transmission. 5.2 Biological control, using Bacillus thuringiensis preparations such as bt or hd-1 or Helicoverpa armigera polyhedral virus spray at the peak of egg hatching, with an amount of 10 billion/g live spore Bacillus thuringiensis 200-250 times liquid and 1 billion One / g cotton bollworm prismatic polyhedra virus wettable powder sprayed with 800 to 1200 grams per 667 square meters. 5.3 Chemical control: focus on catching the hatching period of eggs until the larval second-instar period has not yet penetrated into the fruit. It can use 2.5% of Baoyou EC 2000-3000 times, or 5% of Mengmeng EC-1000-2000 times. Liquid, or 5% Sodium Chloride 1000-1500 Emulsion, or 3% Moban Emulsion 1000-fold, or 15% Naphtha Suspension 2000-fold, or 5% Fluoro-belluron (Cytosine Sulfate) Emulsion 1500-fold Alternating spray. 6 Roots and roots 6.1 Agricultural control: Do not apply unfermented manure and cake fertilizer, and fertilize to avoid exposure to the surface. The leek is not chased after applying manure, and the garlic must be planted with garlic and peeled; the melons and beans should be soaked and germinated before sowing, and the bottom water should be poured to promote early emergence. 6.2 Chemical seed dressing: Use 40% diazinon agricultural powder dressing, the amount of which is 0.3%-0.5% of the seed weight; before sowing, use dizifon agrochemical 50 grams or 80% dichlorvos EC 1000 times Apply or mix with base fertilizer. 6.3 Control of adult worms: At the beginning of adulthood, at 9-11 a.m., it is when the adult is most active. 50% phoxim EC 800 times, or 2.5% chlorinated EC 3000 times, or 1000 times trichlorfon crystal, or 40% equine EC 3000x spray, pay attention to the last medication distance harvested not less than 10 days. 6.4 control larvae: use 50% of phoxim EC 800 times, or 48% of Loester Ben EC per (mu) 150-200 grams of water 1000 kg pouring root, each pier of leek irrigation liquid about 200 ml. Or use 1.1% matrine powder 1500-2000 times to irrigate the roots, matrine can also be used for 2-3 kilograms per (mu), mixed fine soil 15 kilograms along the pier cast, 3 days after watering. After the first knife, use 2 kg of fine soil to spread it on the root and then water it 3 days later. 6.5 Prevention and control of yellow house borer damage in greenhouse: The selection of strong and non-mosquito roots will prevent the earthworms from entering the greenhouse with roots. After the occurrence of fleas, the use of non-systemic drugs such as 90% trichlorfon 1000 times, or 50% phoxim 1000 times, or 1.1% matrine powder 2000 times Irrigation root, pay attention to the final distance from the drug Harvesting must not be less than 10 days. 7 Aphids 7.1 Dispose of the broken leaves and leaves in time after harvest, remove the weeds, remove the insects, and bring them out of the shed for treatment. 7.2 Yellow plate inducement: Refer to greenhouse whitefly control methods. 7.3 Silver gray film avoidance: Ground cover with silver gray film, 5 kg for each (mu) of land, the method of operation with a transparent film. A 10-15 cm wide silver film strip “hanging bar” is used around the booth and 1.5 kg of film is used per (mu). 7.4 Chemical control: When aphids occur, use 50% Pipa 2000-3000 times solution (poor for guava), or 10% imidacloprid WP 1000-1500 times, or 0.5% veratrine (guard bird) The alcohol solution was sprayed with 800 times solution and 3% mibimille oil 1000 times solution. 7.5 Pharmacy Smoking Shed: Before the shed is covered in the shed, use 22% dichlorvos smoke agent to smoke, the specific method with the greenhouse whitefly control. 8 Underground pests include fleas, mites and golden worms, and 90% trichlorfon or 50% phoxim 800 times can be used to root.
