Winter scraping fruit bark better than spraying

As the saying goes: “It is necessary to eat pears and scrape the bark.” The scraping of fruit trees is an important measure for orchard management in winter. It not only helps to increase tree vigor, prevents premature tree aging, but also eliminates wintering in the cracks in the barks. Bacteria and pests reduce the base number of overwintering, control or reduce the occurrence and damage of some diseases and insect pests in the coming year, thus receiving the control effect of “do not apply pesticides and win pesticides”. Comprehensive surveys have revealed that 80% to 90% of overwintering larvae are reduced in scraped orchards, larvae of Mythimna separata, and P. sinensis, and 60% to 80% in apple borerworms and pear carps. Hawthorn red spiders are reduced by 70% to 80%.

The winter shave of fruit trees can be carried out after defoliating from fruit trees to before sprouting in late spring. The main reason is to scrape off the rough skin and skins on the trunk and main branches. The degree of scraping is to scrape off the light brown skin. It is better to see green and white. When scraping the skin, a plastic cloth should be laid under the tree to collect scraped bark and debris, and be deeply buried or burned. For fruit trees with rot and blight disease, smear with Fumei arsenic or lime sulphur should be applied after scraping.

Varicella Vaccine(Live)

1.Good safety of gelatin-free.The first lyophilized Varicella Vaccine, free of animal gelatin, was invented and produced in China, which can significantly decrease the ratio of anaphylaxis incidence .

2.Long validity period for good stability. The first approved varicella vaccine with 36 months of validity period in the world. The application of BH-2 stabilizer with own IP rights (Chinese patent granted No.: ZL200910138411.6, International patent application No.: PCT/CN2009/001405) greatly enhances the stability of the product and ensures the validity period for 36 months under the storage condition.

3.Better protection with high titer and immune performance. It`s documented that compared with the varicella vaccine of low titer, high titer vaccine can reduce breakthrough cases by nearly 75% in vaccination. Among all released batches of Varicella Vaccine from BCHT, the titer is not less than 10000 PFU/dose tested by National Institutes for Food and Drug Control.
