Insect spray for plants

Insecticidal aerosol security has always been to manufacturers distribution department, consumers and administrative departments concerned.Its security is mainly related to the toxicity and combustibility of aerosol two aspects.

1. The insecticidal aerosol toxicity of commonly used insecticidal aerosol mass ejection agent, solvent, effective ingredients have certain toxicity.In the seventy s because of CFC (chloride fluorocarbon class) on ozone depletion has been gradually restricted and prohibited use;In the eighty s and put forward the VOCs (volatile organic compounds) to the environment pollution hazard, visible insecticidal aerosol direct harm to the ecological environment to the survival of humans, eventually threaten the human survival, safety so semeai on producers should strictly abide by the international regulations to limit of harmful substances or disable in aerosol.Usually by the following test semeai aerosol insect toxicity evaluation.

1) the acute oral toxicity and acute dermal toxicity, LD50 to the lethal dose or half lethal dose, said unit expressed in mg/kg, the greater the LD50 value of products, said the lower the toxicity of compound, namely the safer.

2) acute inhalation toxicity, LC50 said that lethal concentration or median lethal concentration, unit expressed in g/l.

Some producers that the greater the effective ingredients of toxicity of insecticidal aerosol or use concentration is higher, it shows the insecticidal effect of the more obvious, so they to blindly pursue the products of biological effect, and the use of high concentration and high toxic substances, the product used in the bedroom, and one contact for a long time, will cause serious damage to human body health.In fact a kind of good insecticidal aerosol formula is the best combination of a variety of ingredients, not only insecticidal effect is good, and using low concentrations, the toxicity is low and mammal.

2. The combustibility of insecticidal aerosol mist burning chi has become the important issue of attention, every year the economic loss caused by aerosol products of combustion and explosion shocked by the ambassador of the people.According to GB/T14449-1993 test method measured the flame to extend the maximum length of products, so as to determine the product's relative combustibility.General insecticidal aerosol flame length of 40 cm.Product of a relatively combustibility, should improve the formula, reduce its combustibility.Foreign demands in insecticidal aerosol cans labeled burning level, easy to identify and difference processing.

Thus, the influencing factors on the quality of the insecticidal aerosol products is various, both mutual relationship between various factors, and restraining each other.Because insecticidal aerosol in China starts late, recently developed rapidly and made insecticidal aerosol product quality in our country there are quite a lot of problems.In terms of aerosol production manufacturer in shandong province, many manufacturers of technical personnel lack of regular and systematic learning, technical personnel business level is not high, some manufacturers crude production equipment, production technology and quality inspection is not perfect, not form a complete production line, stays in the state of mill type, even the most basic of acute leak check, water bath, don't have, not to mention the fog particle diameter, injection rate, injection process and the quality of the spray Angle detection.In addition, as the supervision and inspection departments at all levels should strengthen the management, strictly in accordance with the national standards for testing seriously, to prevent bad products into the market to ensure the quality of insecticidal aerosol products.
