Description
SPECIFICATION
Pesticidal triazines
The present invention relates to a method of using 2,4,6-triamino-1 ,3,5-triazines for treating parts of plants which are put into the soil, such as tubers, bulbs or seed grain (seeds of cultivated plants) for protecting said seeds, and parts of plants developing from them, against attack by phytopathogenic pests.
The 2,4,6-triamino-1 3,5-triazines eligible for use in the practice of this invention are characterised by the formula
wherein R, is cyclopropyl (compound A) or isopropyl (compound B).
Compound A of formula I, wherein R1 is cyclopropyl, is disclosed in German Offenlegungsschrift 2 736 876, and compound B of formula I, wherein R, is isopropyl, is disclosed in J. Med. Chem. 10(1967), 457, as insecticide.
Surprisingly, it has now been found that, after treating seeds with the two compounds of formula I, not only seeds of cultivated plants, such as tubers, bulbs or seed grain, but also the parts of plants developing from them, are accorded long-term protection against damage caused by eating and sucking insects or
representatives of the order Acarina.
Accordingly, the present invention relates to a method of using 2,4,6-triamino-1,3,S4riazines of formula
I for controlling insects and representatives of the order Acarina, which comprises pretreating the seeds of useful plants, in particular of cotton and rice, with a compound of formula I.
It has been found that seed dressing is a particularly useful method of treating the seeds. The compounds of formula I can be added in the form of solid or liquid formulations to a seed dressing apparatus. The seed dressing operation is usually considered as completed when the active ingredient has been uniformly distributed on the seeds in the specified concentration.
Depending on the per se known method of treating (dry, moist, wet or slurry dressing as well as pelleting), treatment of 100 kg of seeds is effected with 1 to 50 kg of a solid or liquid formulation which contains 5 to 75% of a compound of formula I. The conventional solid or liquid formulations of compounds of formula I can be used for the seed dressing.
Formulation Examples (throughout, percentages are by weight)

The following Examples further illustrate the present invention.
EXAMPLE 1
In a glass bottle, 100 g of cotton seeds are dressed with a 10% emulsifiable concentrate of compound A by rotating and shaking the bottle. The amount of dressing is 2 g and 5 g respectively of compound A per 100 g of cotton seeds.
Cotton seeds which have been treated with 2% and 5% of compound A are sown in pots. Three cotton plants in the 3--4 leaf stage which have been grown from these seeds in a greenhouse at 250-300C are populated with 20 freshly hatched Spodoptera littoralis larvae in the L1 stage in a 20 litre container. The container is then covered with a cloth. A count of living and dead Spodoptera littoralis larvae present on the cotton plants is made 4 days after infestation.

The dressing contains 2% of compound A per 100 g of rice seeds.
Rice seeds which have been treated with 2% of compound A are sown in pots. Two weeks after
emergence, the rice plants grown from the dressed seeds are infested at weekly intervals with nymphs of
Nilaparvata lugens (N3). Each plant is populated with 20 nymphs. A count is made of living and dead rice cicadas present on the rice plants 5--8 days after infestation.
