Pesticide Application Methods and Analysis of Common Questions About Microbial Pesticides
What problems have you encountered when using pesticides that you are not aware of? See if any of the questions below are what you want to ask, and let us take a look together.
Biological pesticides refer to pesticides produced from natural materials, such as animals, plants, and microorganisms, which are relatively harmless to living things and highly specific in action. According to the Guidelines for Physicochemical and Toxicological Testing of Pesticides, amended and promulgated by the Council of Agriculture, Executive Yuan on March 17, 2017, biological pesticides include three major categories: natural materials, microbial preparations, and biochemical preparations.
How long does it take for biological pesticides to show an effect after application?
Generally speaking, if applied once a week, it must be used continuously at least 3 times or more, or used continuously over the medium to long term, before the effect gradually appears.
Can biological pesticides be used in organic farming?
Even if a biological pesticide license has been obtained and there is no problem of chemical pesticide residues, it still cannot directly claim to be "suitable for organic agriculture" under the law. Manufacturers must apply to the Agriculture and Food Agency for the "Selection and Recommendation of Brands of Commercialized Materials for Organic Agriculture," and only after passing review can it be listed on the label.
Many people in the market cultivate microbial pesticides on their own. How can quality be effectively maintained?
There are not many reliable brands on the market, the choices are limited, and the prices are not cheap, so people have no choice but to cultivate them on their own. However, without seeking expert assistance to test the bacterial count and strain purity, the probability of culture failure and contamination by miscellaneous bacteria is very high.
When using Bacillus subtilis or Bacillus amyloliquefaciens, can other beneficial bacteria such as endomycorrhizal fungi, Bacillus thuringiensis, actinomycetes, or Trichoderma be added at the same time?
Bacillus subtilis or Bacillus amyloliquefaciens may have antagonistic effects on some bacteria or fungi. It is generally recommended not to rashly add different strains for use together.
Does an appropriate amount of Bacillus subtilis or Bacillus amyloliquefaciens have a root-promoting effect? Does an excessive amount really inhibit roots?
As long as the product quality is excellent and the manufacturer is large enough, the recommended dilution ratio will be indicated.
Do microbial pesticides need to be activated before use?
As long as it is a pesticide product, it will have specifications, and at least the content of active ingredients will be indicated. When the government originally approved the biological pesticide license, it already presupposed that the product would be used directly according to the packaging instructions.
