Suspension concentrates
View Patent ↗The present invention relates to novel suspension concentrates of certain agrochemically active compounds, to a process for preparing these formulations and to their use for applying the active comprised therein.
1. Composition, comprising
from 1 to 60% by weight of at least one systemic agrochemically active compound selected from the group consisting of imidacloprid, thiacloprid, and spirotetramate,
from 1 to 50% by weight of at least one penetrant from the class of the polyalkoxytriglycerides obtainable by ethoxylation of rapeseed oil, the degree of ethoxylation being from 60 to 80% by weight,
from 1 to 25% by weight of at least one adjuvant from the group of the polyglycerols or polyglycerol derivatives obtainable by copolymerization of
a) glycerol,
b) phthalic acid and
c) coco acid,
from 1 to 20% by weight of at least one nonionic surfactant and/or at least one anionic surfactant, and
from 0.1 to 25% by weight of at least one additive selected from the group consisting of antifoams, preservatives, antioxidants, spreading agents, colorants and/or thickeners.
2. Composition according to claim 1 , wherein the active compound comprises imidacloprid.
3. A method for controlling animal pests or phytopathogenic fungi, comprising applying an effective amount of the active compound of said composition according to claim 1 to animal pests, their habitat or plants.
4. Method for controlling animal pests or phytopathogenic fungi, comprising applying a composition according to claim 2 in diluted or undiluted form to animal pests, their habitat or plants such that an effective amount of the active compound comprised therein is applied.
5. Method for controlling animal pests or phytopathogenic fungi, comprising applying a composition according to claim 1 in diluted or undiluted form to animal pests, their habitat or plants such that an effective amount of the active compound comprised therein is applied.
6. Composition according to claim 1 , wherein
the active compound is present in an amount of from 5 to 50% by weight,
the penetrant is present in an amount of from 2 to 30% by weight, and
the adjuvant is present in an amount of from 2 to 15% by weight.
7. Composition according to claim 1 , wherein
the active compound is present in an amount of from 10 to 30% by weight,
the penetrant is present in an amount of from 5 to 20% by weight, and
the adjuvant is present in an amount of from 5 to 10% by weight.
8. Composition according to claim 1 , wherein the active compound comprises spirotetramate.
9. Composition according to claim 1 , wherein the active compound comprises thiacloprid.
10. Composition according to claim 1 , wherein the active compound comprises imidacloprid and spirotetramate.
11. Composition according to claim 1 , wherein the adjuvant comprises
19.9 to 99% by weight of structural units derived from the glycerol,
0.1 to 30% by weight of structural units derived from the phthalic acid, and
