1、Timing of use

(1) The use of pyraclostrobin must be in advance, to prevent disease as a protective agent, or in the early stages of disease such as pre-sowing, seedling or planting, etc. The advantages of the agent can be more fully realized.

(2) pyraclostrobin is to anti-effective and persistent, fast-acting and other targeted fungicides compared to the still slightly insufficient, it is best to use with other fungicides or with compounding agents.

(3) Pyraclostrobin has a single site of action, so the resistance starts relatively quickly. The number of times it is used must be controlled to avoid accelerating the emergence of resistance.

(4) Strong permeability allows pyraclostrobin to affinity well with the leaf surface, greatly enhancing the preventive effect and persistence period, but pay attention to the generation of drug damage. Especially in the crop seedling nursery period, crop growth and high temperature and high humidity conditions, pyraclostrobin use of too high a concentration will have a certain risk of drug damage.

2、Pharmaceutical and other issues

(1) Will the powder be easily damaged?

Pyrazole powder will not cause drug damage. To tell you how the drug damage is caused, if you have used MnZn powder, you should know that it is a relatively easy to cause drug damage, a lot of companies in pursuit of cheap, like to use the kind of big bags in the fruit trees, ZnMnZn must be the complex state, if not the complex state of the manganese ions are easy to release this prematurely, and then the powder can not meet the requirements, it is easy to occur drug damage. The powder will not meet the requirements, and drug damage will easily occur.

If pyraclostrobin is diluted reasonably, it will not be harmful. However, if there is a local precedent of pyraclostrobin poisoning, it is recommended to experiment first.

(2) Will it be harmful if I mix it with gibberellin (920)?

Under normal circumstances will not produce drug damage, unless you look at what crops, for example: in grapes, and 920 erythromycin mixing may produce drug damage, not because of pyrazole, but because of the powder will be adsorbed around the drug in a piece, resulting in local concentration becomes larger and produce drug damage, but this requires practical operation, most of which is the result of people arbitrarily increase the amount of dosage and caused.

(3) If it is used for plant health care, can it be used more than once?

It can not be used for many times, although it has health care effect, but it will produce resistance if it is used for many times.

(4) What can be done to keep pyraclostrobin alive?

First of all, have a correct understanding of pyraclostrobin, it is a good component, but it is by no means a panacea. The product that is put in the right place is a good product.
