Abstract

PURPOSE:To mitigate or avoid the development of chlorosis without impairing inherent plant growth regulatory effects by continuous combined use, either simultaneously or near simultaneously, of a phosphoric acid with 2-chloroethyl trimethylammonium chloride (a plant growth regulator). CONSTITUTION:A continuous combined use of (A) a phosphoric acid (pref. orthophosphoric acid, metaphosphoric acid, pyrophosphoric acid or salt thereof), either simultaneously or near simultaneously, with (B) 2-chloroethyl trimethylammonium chloride as an established plant growth regulator is made at an amount of 1-50g/a of the component A (in terms of P2O5) and at the molar ratio A/B=(1:10)-(10:1) [pref. (1:3)-(3:1)]. Thereby, the component B can be used without impairing the effects inherent in the component B with the development of the chemical injury (chlorosis) potential to crop mitigated or avoided, even under such meteorological conditions as to liable to develop chlorosis. Furthermore, improvement of stability of the above-mentioned effects due to the increase in dosage of the component A and/or growth-promotive effects due to the fertilizer response of the phosphoric acid, etc., will be expected.

<Conventional technology> Chlormequat is used in field crops such as wheat, potatoes, tomatoes, brocades, and husks, as well as hibiscus, azaleas, carnations, oleanders, wildflowers, geraniums, begonias, etc. Incesti Otsu As a growth regulator for ornamental plants such as Rose of Sharon, it mainly suppresses stem elongation and causes defects.
It is used to increase resistance to The method of use is to absorb it through the roots through soil irrigation,
There is a method of absorbing it from the foliage by spraying it on the foliage.
At the dyeing stand where foliage spraying was performed, the type of plant, previous growth history of the plant, weather conditions before and after spraying, other herbicides and insecticides, etc.
Mixed use with M agents, t or spray concentration may cause chlorosis in the sprayed crops, and extreme caution is required when spraying. Pest Control Standards, Herbicide Usage Standards, Plant Growth Regulator Usage Standards” Early Year 2nd Edition) <Problem to be Solved by the Invention> As mentioned above, when using a chlormate pot as a plant growth regulator, Although it is essential to take great care to prevent chlorosis from occurring in a single crop, the various factors involved in the j1 curse of chlorosis are not fully understood, and mulberry plants may be grown under inappropriate conditions. There may be cases where spraying is unavoidable.
