Correct selection of pesticide spray additives

In today's agricultural production, pesticide spray additives are quite popular. Pesticide spray additives are divided into two categories, namely, co-agents, including surfactants, wetting agents, oil-based adhesives, and penetrating agents; special-purpose spray additives, including buffers or acidifiers, or pH changes. Agents, water conditioners, anti-drift agents, thickeners, admixtures. There are a few things to note when choosing pesticide spray additives:

1. Select agricultural spray additives specially developed for agriculture and forestry, and do not use industrial products or household detergents or detergents to avoid damaging the activity of pesticides.

2. Many pesticide formulations already contain the necessary additives to improve the performance of pesticides. Do not add spray additives without authorization.

3. Make sure that the spray adjuvant to be used has been thoroughly tested for efficacy. Products that are in doubt or uncertainty should be used in large areas after a small-scale test.

4. The recommended pesticide adjuvant may be changed due to changes in the dosage form and application technology procedure, and should be selected correctly when used.

5. Improper use or excessive use of pesticide spray aids may result in reduced efficacy or phytotoxicity. The labels of pesticides and auxiliaries should be read carefully to ensure that the selected auxiliaries match the application site, the target pests, and the medical devices, and they must match the pesticides used.

Influenza Vaccine

Influenza Vaccine, Live, Nasal, Freeze-dried Exclusively authorized by the WHO in China WHO
Influenza Vaccine, Live, Nasal, Freeze-dried is a cooperative project with the WHO, which has been included in Global Action Plan for Influenza Vaccines (GAP)[1]. Hundreds of millions of doses have been used in the world, and Changchun BCHT Biotechnology Co. has the exclusive right of production and

operation in China.

Intranasal spray administration, no injection and no pain


The vaccine is inoculated by nasal spray, equipped with nasal spray device, and only needs to spray once a year in two nostrils to prevent influenza.
Mucosal immunity + Cellular immunity + Humoral immunity

After influenza virus attacks human body, it widely exists in nasal cavity, respiratory tract and other mucosal parts, as well as in body fluids and cells.
Vaccination of Influenza Vaccine, Live, Nasal, Freeze-dried can quickly stimulate the triple immune response of human body, and carry out defense
against viruses in different parts:
·Intranasal administration can produce mucosal immunity (IgA antibody), which forms the first immune defense line in the nasal cavity.
·Produce humoral immunity (IgG antibody) to remove influenza virus from body fluids.
·Produce cellular immunity (T cells) to remove influenza virus from cells
3+N More extensive protection
The production strains are recommended and supplied by the WHO every year.
The vaccine can not only effectively resist the vaccine strain, but also produce cross immunity to other subtypes of influenza virus.

Produced with SPF embryonated eggs


The chick embryos for vaccine production comes from SPF (specific pathogen free) chicken flocks, so the risk of exogenous pathogenic microorganism

pollution is excluded.


Free of inactivator, split agent and preservative

High protection and fast antibody production

This is the first influenza vaccine in China that has been evaluated by the protection effect of etiology in clinical stage. The protective effect of phase III
clinical trial is consistent with the literature[2] .
First, the immune barrier was formed in the nasal mucosa after LAIV vaccination. It has been reported that the antibody of nasal mucosa can be
produced in 3 days[3], which greatly shortens the time for vaccine to produce
protective effect.
