Not only can help digestion, solution spicy and protect the gastrointestinal and liver, kidney tonic, is a new type of health care Lai. Shanghang County introduced trial planting, demonstration, and promotion from Japan in 2001. It has demonstrated ease of cultivation, vigorous growth, and high yield in the past three years. It is highly welcomed by consumers. Its common pest occurrence and control techniques are reported below.

1 The disease can be infected at the seedling stage and adult stage. Shanghang County began sowing after the temperature reached 15°C in mid-March. When the seedlings were 20cm long, the diseased spot spread from the leaves to the main stem, making the stem thin and brown, causing the whole plant to wilt or fall. Leaf disease mostly starts from the lower tip or the leaf margin of the plant, and the dark green water spot does not cause lesions at the beginning of the disease, and it turns brown after expansion. Prevention: Grasp the initial stage of disease with 72% manganese zinc frost urea WP (Kelu) 500 times or 69% Anke manganese zinc WP900 or 64% WP400 or 58% metalaxyl WP500 Spray once every 7-10 days, control 2 or 3 times.
2 Viral disease Virus disease is the major disease in the production of Okra. According to the investigation of planting in my county, the adult plant is more serious than the seedling stage. The onset time is generally from May to September. The whole plant was affected after infection with the plants, especially at the top of the young leaves. The leaves showed mosaic or brown markings. Infected early, the plants are short, with little or no fruit. Control measures: Do not leave seed from diseased fields, choose disease-resistant varieties, use 5% bacteria to clear WP400～500 times liquid or 20% virus AWP400 times liquid or 15% plant disease spirit 1000 times or 83 increase resistance agent in the early stage of disease. Control 3 times, once every 7-10 days.
3 The poisonous caterpillars are mainly responsible for the seedling stage, and often eat the leaf meat as a short cut after emergence. In severe cases, only leaf veins remain. Control: Disperse 10% EC 1500-fold or 5% fipronil SC 1500-fold or avermectin EC-decavonmethrin EC 3000-fold spray.
4 Liriomyza canadensis can be damaged during the whole growth period, and it mainly damages the leaves. Can be controlled with 1.8% afordin EC (avermectin) 5000 times solution or 52.25% farmland EC 1000x solution or 48% Lethburn EC 1000x solution or 5% fipronil SC 800x solution.
5 Aphids can occur throughout the growing season, and are more severely affected by adult plants. Can be used imidacloprid pesticides such as 10% net once, 10% net, 10% Dagongchen 3 000 times control.
The 6 moths of Shanghang County mainly occur from May to September. The harvest period is more serious, often eating the leaves into nicks, and the severe ones eating into a net. Control agents: 52.5% security EC1000 times or 10% EC1500 times or 52.5% farmland EC1500 times or 2.5% dishes like SC1200 times or avermectin + 5000 times Kung Fu.
7 Ants often gather on flower plants after flowering. Prevention: Use 48% of Lorean EC (domestic chlorpyrifos) 1000 times spray or 5% Frigid SC 1 500 times spray or use Ruijin special 0.3% of the liquid mixture of wood chips scattered in the ants out of the trap.
Okra harvesting interval is short, the use of pesticides must use suitable pesticides for pollution-free vegetables, spray not try to spray on the flower or tender fruit.
SanQiang medical companies specializing production Indicator.
Medical Indicator in the verification of the sterilization procedure,although the sterilization effect can be evaluated through the monitoring of certain parameters of the sterilization process,the degree of killing of the biological indicator is the most intuitive indicator for evaluating the effectiveness of a sterilization procedure.Commercially available standard biological indicators can be used,as can spores prepared with the most resistant micro-organisms isolated during daily production monitoring of contaminants.In the biological indicator verification test,the D value of the spore under the actual sterilization condition needs to be determined,and the spore purity and quantity are determined.When verifying,the microbial indicator of the biological indicator should be larger than the routine detection of microbial contamination,and the tolerance is strong to ensure that the sterilization procedure has greater safety.In the final sterilization method,biological indicators should be placed in different parts of the sterilizer.And avoid direct contact with the indicator to be sterilized items.The biological indicators are sterilized after being sterilized according to the set conditions,and cultured in a culture medium respectively to determine whether the spores in the biological indicator are completely killed.
