Vegetable defense against second generation cabbage caterpillar, diamondback moth
Insect killers use insect traps to entice the principle of tropism on light sources of specific wavelengths. Field installation and opening of the frequency-vibrancy insecticidal lamp has a good trapping effect on the diamondback moth, nocturnal insect pests and adult insect pests. Insect-resisting nets block areas where conditions permit, and field-covered insect-repellent nets block the spawning of diamondback moth and cabbage caterpillars, protecting cruciferous vegetables from harm. Sexual sedation and sex pheromone suspend 4 to 5 Plutella xylostella sexual traps and sex attractant lures per acre field, which can induce a large number of adult males of Plutella xylostella. Or put 30 to 40 diamondback moths on each mu field to maintain high concentrations of sex pheromone in the field and disrupt pest mating, which can reduce effective egg production. Bio-pesticides are used to control 12.5 to 17.5 ml of 10% suspension of doxorubicin per acre, or 20 to 33 ml of spinosyn suspension of 60 g/l, or 166 to 200 ml of a 0.3% matrine aqueous solution, or 0.4% osthole emulsifiable concentrate 80 to 120 ml, or 16,000 IU/mg of Bacillus thuringiensis water dispersible granules 100 g, or 100 million spores/ml of Stabilis bacilli suspension 50 to 100 ml, or 1 billion pb/ml beet night Moth nuclear polyhedrosis virus 50 to 100 ml, or 0.3% azadirachtin EC 60 to 90 ml, or 1.8% abamectin EC 30 to 50 ml, 45 kg of water evenly spray. Chemical control is controlled from the peak of egg hatching to the incubating period of young larvae (before the third instar) and is controlled at intervals of 5 to 7 days. The number of medications is determined depending on the pest situation in the field and the harvest time from the vegetables. Can use 5% chlormethenone benzamide suspending agent 30-55 milliliters per acre, or 15% indoxacarb suspending agent 10-18 milliliters, or 10% chlorfenapyr suspension 33.3-50 grams, or 10% fenthrin Suspension 80 ~ 100 grams, or 2.5% deltamethrin wettable powder 40 ~ 60 grams, add water, 45 kg uniform spray. In accordance with the ban on the use of pesticides to use pesticides, vegetable market must strictly comply with the provisions of pesticide safety interval. Pay attention to the rotation of pharmaceuticals to delay the emergence of pest resistance.
It can be used for surgical operations, patient treatment; epidemic prevention and inspection in public places; disinfection in virus-contaminated areas; and can also be widely used in military, medical, chemical, environmental protection, transportation, epidemic prevention and other field
By setting a protective collar, the neck of the operator can be kept warm and protected. The provision of a hand guard is helpful for the surgical staff to temporarily place their hands in the hand guard while waiting during the operation, which plays a protective role and is more in line with the principles of aseptic operation and occupational protection. surgical gown,disposable surgical gown,personal protection,medical equipment Shanghai Rocatti Biotechnology Co.,Ltd , https://www.shljdmedical.com
By setting the shrinking cuffs, it is beneficial to make the cuffs fit the wrists, prevent the cuffs from loosening, and prevent the gloves from slipping off during the operation and the operator's hands are exposed to the gloves.
The design of the new humanized protective surgical gown has been improved in the key areas of the gown. The forearm and chest area are double-thickened, and there are handguards in front of the chest and abdomen. By arranging reinforcing sheets (double-layer structure) in key areas, it is beneficial to improve the water-permeability of surgical gowns and improve safety.
