mu 3-5 pounds.

Pepper making of pest control is a quite essential part, it has a direct bearing on the merits of quality pepper, chili and even the class of output produced by the success or failure. It is a systematic project, not simply a pest problem after the use of some medicine, especially with the perennial promotion of quality of life and China's , adhere to the Alternately, rotation using some efficient, low toxicity, low-residue pesticides, the pest control among the control concordance, integrated pest of some common, specifics, I consider that prevention should be the following aspects on.
one, the alternative of varieties resistant to insect pests : purification and rejuvenation with accustomed varieties do well to cultivate new varieties, culling of varieties resistant to insect pests, maim, transgenic varieties. never mighty plants on the seed disease.
Second, nurturing seedlings: fine management, to feeble to stay muscular, stay Qubing Zhuang.
Third, improve disinfection: (a) seed sterilization: 1, Shaizhong. Shaizhong 2-3 days before sowing, to kill some germs .2, hot water pretreatment. rinse the seeds for afterward use 3 times the amount of seed soaking in peppery water at 55 degrees (that is, three on a cool open), fast stir until water temperature is 30 degrees, stop, and then soggy for 12 hours, germination .3 sowing, soaking agents. the seeds in 15-20 degrees water inundated for 15-20 minutes, remove the seed husks, soaked 4 hours and then clear, chilly and dry the surface of water with 1% sulfuric mordant solution soak for 15 minutes, remove and rinse after repeated 5-6 times, primed seed. (b) of the bed Disinfection: 1, water formalin (formaldehyde) dilution. in the first half of sowing, first Chuangtu loose dug, and then water. with is this: per square measure seedbed formalin 450 ml, water 18 - 36 kg (wet and dry conditions, as Chuangtu) .2, mores, multiple vaccine remedy soil. per cubic meter of 250 g of fine soil treatment, mixed through the mixing .1 / 3 of the bed surface, 2 / 3 Cover seeds. (c ) Greenhouse disinfection 1, transplant the first half, the Commission closed hot sunny day 7 days a stuffy laboratory, you can kill maximum bacteria .2, generally secondhand in the early worm.
Fourth, agricultural control, (a) Choose the taint. regardless of mattress, or elect the year field namely not planted peppers, eggplant, tomatoes and other Solanaceae and melon light non-sticky soil and the best, to empowerment row of soil organic stuff content. (b) cultivating winter irrigation and kill overwintering eggs. (c) and wheat intercropping on microclimate, reducing ailment and pests. (d) Mulching. `to amend the root surroundings apt depress ailment, and promote early seedling germination.
5, physical control, according to the more light of the pest, agreeable savor of, trends and other principles of color, lofty in the moths of lofty pressure mercury bulb, black light technology to poplar , oil yellow boards, integrated moth sex pheromone trap agent, focusing in increase to kill. Practice has proved namely the upon method of economic, secure and efficacious.
six, biochemical control
(a) of the disease. pepper diseases there are numerous different virus disease, anthracnose, blight, damping-off disease, blight, soft rot, scab, sunburn, root rot, white spot, powdery germ and other more than twenty category, particularly in the larger boron, greenhouse, etc. conservation to high temperature, high pressure environment, more conducive to disease incidence, prevalence, is based on the substantial, occurred in North China introduced more of the retinue diseases:
1, viral disease. called mosaic disease, mad disease, a dog ear disease. (1) symptoms of ailing small, leaf thickness, leaf rugged, color yellow, shades of white, small and less Results pepper, few lateral roots, mosaic and necrotic spots, branch or stem produced brown necrotic streaks or dieback, early leaf emergence, flower, fruit drop, bunched bough, fruit small and slow growth, yellow-green spotted, or deformity. (2) control measures 1 spray passivation agent, or honey locust bean flour 1,5 kg flour 30 kg of water,then we小朱 namely object namely has reserved it from me, sprayed pepper .2, the early stages, spraying 1000 times, or 1% potassium superphosphate leach solution to improve the resistance of .3, spray fluid grams of 800 times or spiritual disease .4 A and other viral agents, spray 0,3% of the 86 preparations, in the first half planted, after transplanting in January and the spray of a sprout.
2, anthrax. is a mutual and caustic disease risks . (1) symptoms. stems, leaves and fruit can be infected, early lesions showed Shui Zizhuang into the central white spot circled by dark brown spots on a prevalence of watery hot like the same listless, deciduous, drought the rain, sudden rain, sunny, high humidity is conducive to disease epidemics. (2) control measures, 1, copper sulfate 1000 times, 1000 times 70% thiophanate-methyl, mancozeb 400 times 70%, 70% of the ratio bacteria Qing 500 times, 65% thiram wettable powder 600 times, 2% of peasants can also be used against hurling, high temperature water sooner or later, do not gush hot summer days at noon, due to explosions of the disease lightly.
3, disease. occur quickly destructive disease .1, symptoms. forking stems at the black to black smudges, twig constriction cutback, the starting of dark brown stain-like lesion, Park-shaped, dry, white, an brown, moisture, foliage soft rot cozy to fall off. soil-borne, water borne disease, spread rain sputtering, high temperature and high humidity is profitable to disease epidemics 2, control measures: Intercropping with garlic, mild disease; seedbed humidity, spreading ash or fine dry soil; copper sulfate, acres scatter 3 pounds, can be mixed with fine sand or fine soil, watering light irrigation; 50% Swiss aluminum and copper toxicity 1000 times, 66% CDC800 times, 500 times or 70% mancozeb the Bordeaux mixture 1:1:200 in 7-8 months before or afterward the rain the afterward daytime spraying irrigation control.
4, the damping-off, damping-off. seedbed diseases, fold root or dry, low temperature, high temperature,shanghai escort, low light are easy to cause the disease. 1000 times with 70% thiophanate-methyl spray.
5, soft rot, scab. are bacterial disease, early disease Shuizi Zhuang, developed into a bag-shaped dark green watery pus bubble. spray 200PPM or Bordeaux mixture of agricultural streptomycin, neomycin new plant, 7 days time.
6,shanghai escort, sunburn disease. (1) symptoms. physiological diseases, fruit rot, disappear bright side hardens, water detriment thinning, light yellow or white. (2) obstruction and control amounts. reasonable close planting, to prevent the leaves; water cooling or spray of water, 10 years antecedent, 10 kettles / mu; bronze sulfate spray 1,000 periods. sprayed boron, 40 degrees warm water 50 kg 0,2 kg and sodium borate spray line; afternoon 3:00, spray 0,1% leaching solution of calcium chloride solution or superphosphate, the sometime ought be less than four times. dorsal, leaf ought be uniform and thoughtful.
(b) of the bane. pepper pests are bollworm, tobacco budworm, mole crickets, defended with pearly powder lice, etc., a dozen, are presented in pepper opposition more of the emulating major pest.
1, Cotton habits were alike happened 4 generations a year, favor warm, humid place. and different cotton is not merely in young eggs the front, behind, also. prevention strategy is to reserve their generation, control of the second generation, cumbersome anti 3 generations, 4 generations of sweeping debris. Control measures are: the measure of 15-20 tablets of one hundred eggs, or larvae 5-7 pate. Control measures: (1) biological control: The NPV virus nuclear angular body, BT emulsion,beijing massage, bassiana, abamectin, Trichogramma, caterpillar fungus 6, at 3 years old prior to medicine. (2) irrigation dichlorvos corncob fumigation. DDVP for 50% of the corn cob 30 ml irrigation, 80-100 mu root, pepper sticks field fumigation planes to protect normal enemies. (3) chemical; pesticide spray. kill to death 2000 times, Xin S P 2500 times, 3000 times Deltamethrin spray. (4) insect growth regulator: diflubenzuron spray the night 3000 times, 3.
2, vegetable aphids. likewise known for honey insects, aphids and so on. In occurred 15m25 s, optimal temperature (<28 degrees), dry beneficial to its place, should have early governance principles. (1) silver mulching, avoid aphid effect is obvious. (2) natural enemies: artificial feeding ladybugs, spiders, lacewing, etc., the release of pepper fields. (3) biological control: 80m1000PPM Qingfeng neomycin spray. (4) chemical control of a urine mixture washing: washing powder (neutral): water = 2:1:1000 mix spray Fog .2, pesticides: 50% DDVP 1000 times, 70% of the powder to kill aphids 2000 times, 3000 times Deltamethrin 2,5%, 50% wettable powder pirimicarb 2000 times, 21% kill to death 3,500 times.
3, mole crickets, grubs. (1) drug Valley Traps: 10 pounds of millet or corn grits, boiled half cooked, cooled, dry, and do not stick, mix 90% trichlorfon 120 times 0, 4m0, 5 pounds, mix into the dry with cool to 7, generally 3-5 pounds per acre ravine with a narcotic, can be applied to buried or on the soil surface, but also with species, seedling mix. (2) lure trapping. with wheat bran 10 kg, injected into 30 times 90% trichlorfon to hand shape into groups, casual touch available at the time, irrigation or rain in the evening, sprinkle on the seedlings, plants near the ground, mu 3-5 pounds.
4, whitefly, also known as white moth, greenhouse, greenhouse pests, smaller than the aphids, social dorsal taking nectar leaves fade to yellow, wilt, or even death, easy to coal pollution induced disease occurred in more than ten generations, and aphid action similar trend yellow. (1) yellow viscous oil board killed. (2) Raising and releasing lacewings. (3), Uranus, Decis, buprofezin 2000 times spray. July, memoranda, 1, either worms, the use of chemical pesticides, the resistance gradually additional, so keep in mind when prevention reduce the amount of water. Some of pepper harvesting is the easy way, blindly increasing concentration, less water, the results easy to be poisoned, the control efficiency is meager, poor products, amounting to less than .3 pollution criteria, go is completed, rinse with soap or alkali exposed portions of the body to dodge straight or chronic poisoning. In short, pepper pest control is a systems engineering,toronto escorts, the use of eco-control strategies to maximize the livelihood of ecological balance, to produce safe, high-quality pollution-free chili.
