Abstract
A method of protecting a plant susceptible to attack by a Phylotxeta spp.
insect from said attack which comprises applying to the seed from which the plant grows an effective amount of a chloronicotinyl insecticide or a salt thereof, which insecticide is other than imidacloprid and thiamethoxam.
insect from said attack which comprises applying to the seed from which the plant grows an effective amount of a chloronicotinyl insecticide or a salt thereof, which insecticide is other than imidacloprid and thiamethoxam.
Description
New Method for the Control of Flea Beetles in Canola The present invention relates to a new method fox the control of flea beetles in plants.
At the present tune, there exists a need to protect plants from infestation and damage by flea beetles. This particular problem exists in portions of the North American continent where canola is raised for the value of its oil. At present there is no one-stage chemical treatment effective to protect canola from the damage that is done by flea beetles. In fact, a generally accepted method comprises treating canola seed with lindane (a mixture of 1,2,3,4,5,6-hexachlorocyclohexanes), combining with granular terbufos (S-tert-butylthiomethyl O,O-diethyl phosphorodithioate) and then planting the seed/pesticide cotnpositiozt. It is generally known that lindane and other chlorinated hydrocarbon iuasecticides (as well as organophosphates )are being removed from agrochemical markets on a worldwide basis due their generally unacceptable persistency in the soil or acute toxicity to mammals. Thus there exists a need for an improved treatment of canola from flea beetle attack.
An object of the present invention is to provide a new insecticidal treatment of canola seed.
Another object of the preseat invention is to provide a one-stage or one-step treatment of canoia for protection from flea beetle Another object of the present invention is to provide a treatment of canola seed that is more environmentally acceptable thazt the state of the an.
Another object of the invention is to provide a treatment of canola seed that is superior to those in the state of the art.
These objects are roet in whole or in part by the present invention.
The present invention provides a method of protecting a plant susceptible to attack by a Phylotreta spp. insect from said attack which comprises applying to the seed from which the plant grows an effective amount of a chloronicotinyl insecticide or a salt thereof, which insecticide is other than itxtidaeloprid and thiamethoxam.
34 Preferably the insecticide is (E)-N~-[(6-chloro-3-pyridyl)methyl]-N~-cyano-N~
methylacetamidine (acetamiprid or NI-25) The preparation and general uses of acetatz~,iprid are described in US Patent 5,304,566 and in The Pesticide T~lanual, 10'"
edition, Ed. C. Tomlin, British Crop Protection Council, 1994, p.730.
Generally the Phyllotreta spp. is Phyllotreta cruciferae, which may also be known as turnip fly, ctucifer flea beetle, or cabbage flea beetle. Generally the plant is a Brassica spp. plant. Preferably the Brassica plant is Brassica napes ( also known as Rape or Rapeseed) , Brassica rapa (also known as canola), or Brassica juncea (mustard).
The method preferably comprises protecting the plant from the time of etrtergence from the seed from which it grows to flowering of the plant. This is generally the period during which the plant is susceptible to attack by Phyllotreta.
Preferably, the plant is at a growth stage of from the expansion of the plant cotyledon to the sixth true leaf. Preferably the plant cotyledon has expanded.
In general the insecticide is applied to the seed in an amount of active ingredient of fxom 0.1 to 20 grams per kg of seed (g/kg), preferably from 1 to 10 glkg and most preferably from 2.5 to 7.5 g/kg.
The seed treatment step is effected by conventional means of seed treatment known to those skilled in the art of seed treatment.
The present iztvention also provides a method of treating seed to protect the plant from which it grows, the said method cozxaprisiztg applying to the said seed an insectieidally effective amount of a ehloronieotinyl insecticide or a composition comprising the insecticide, which insecticide is other than imidacloprid or thiamethoxam.
The invention also provides the seed so treated by the said method of treatment.
The following non-limiting example provides an example of the invention.
Acetamiprid is applied to canola seed at rates of 7.5, 10, and 12.5 grams of active ingredient per kg of seed. Imidacloprid is applied to carxola seed at rate of 15g/kg of seed. The seed is planted and allowed to grow. At 4, 7, 10 and 14 days post emergence of the plant, damage is assessed for the plants by lookizag for shot-hole damage. All treatments of acetamiprid provide substantially more control than imidacloprid and are generally eduivalent to the two stage lindane + terbufos treatment. At the end of the growing season, there is a general yield increase in plants which are grown from seed that bas been treated by acetamiprid,
