English Science Agriculture
Oidioplan is used by foliar application, soaking both the adaxial and abaxial sides of the leaf. It is suitable for use in both the prevention and the cure of powdery mildew and mildew attacks. It also works as an acaricide against the broad mite and the red spider mite.
When used as a cure repeat the treatment every third day.

Apply in the early morning or late afternoon. Do not mix with acid solutions. A neutral pH solution, around 7, is recommended.

When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.

How to tell the difference between "easy" and "pro" questions:

An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)

A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).

Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.

When deciding between easy and pro, err on the side of pro. Most questions will be pro.

* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

Sorry, 7 is neutral pH.
0 is extremely acidic, and 14 extremely basic.

pH 7 is neutral, so this is just emphasising what is said

Around meaning, in this case, "about", or "in the range of"
