Abstract
The present invention relates to a fungicidal composition for agriculture and horticulture comprising at least one adjuvants and, as an effective component, in effective amounts, N- (1-n-butoxy-2,2,2-trichloroethyl) salicylamide and one member selected from the group consisting of (1) pentachloronitrobenzene and (2) tetrachloroisophthalonitrile. This composition is useful to control soil borne plant diseases such as clubroot disease of Cruciferae crops, black scurf of potatoes and damping-off of cucumber and tomato seedlings.
Description
SPECIFICATION
Fungicidal composition for agriculture and horticulture and its use
The present invention relates to a fungicidal composition for agriculture and horticulture. In particular it relates to a composition comprising, as an effective component, in effective amounts, N-(1n-butoxy-2,2,2-trichloroethyl) salicylamide
and one member selected from the group consisting of (1 ) pentachloronitrobenzene
and (2) tetrachloroisophthalonitriie
This composition is useful to control soil borne plant diseases such as clubroot disease of
Cruciferae crops, black scurf of potatoes and damping-off of cucumber and tomato seedlings.
N-(1-n-butoxy-2,2,2-trichloroethyl) salicylamide (hereinafter referred to as "compound A"), one of the effective components of the present invention is a known compound described in the specification of USP 4,200,632. This compound is highly effective for controlling soil borne plant diseases, particularly clubroot disease of Cruciferae crops. However, when the compound is used at a low concentration, a sufficient fungicidal effect cannot always be obtained on plant diseases caused by
Rhizoctonia sp. and the like.
Pentachloronitrobenzene (hereinafter referred to as "PCNB") is now available on the market as a fungicide against clubroot disease of Cruciferae crops and black scurf of potatoes. Though the compound is effective against the fungi of Plasmodiophora sp. and Rhizoctonia sp, there is a problem of the residual toxicity since it is used in a large amount.
Tetrachloroisophthalonitrile (hereinafter referred to as "TPN") is now available on the market as a fungicide for controlling clubroot disease of Cruciferae crops and damping-off of cucumber and tomato seedlings. However, the sufficient controlling effect cannot be obtained in some cases.
After intensive investigations made for the purpose of developing a fungicide for surely controlling various soil borne plant diseases, the inventors have found that a mixture of compound A with PCNB or
TPN shows a synergistic effect without giving any phytotoxicity on crops which is unexpected from the effect of the respective components. The present invention has been completed on the basis of this finding.
The weight ratio of compound A to PCNB is preferably in the range of 1 :5 to 5:1, preferably 1:1 to 5:1.
According to the present invention in a first aspect there is provided a fungicidal composition for agriculture and horticulture comprising as an effective component, in effective amounts, N-(1-n-butoxy2,2,2-tirchloroethyl) salicylamide and one member selected from the group consisting of (1 ) pentachloronitrobenzene and (2) tetrach loroisophthalonitrile.
According to the present invention in a second aspect there is provided a method for controlling plant diseases caused by fungi which comprises applying to said fungi or locus thereof an effective amount of mixture of N-(1 -n-butoxy-2,2,2-trichloroethyl) salicylamide and one compound selected from the group consisting of (1) pentachloronitrobenzene and (2) tetrachloroisophthalonitrile.
The weight ratio of compound A to TPN is preferably in the range of 1:1 to 10:1, preferably 1:1 to 5:1.
The composition of the present invention may be used as it is or in the form of a mixture with an agricultural adjuvant which improves the effect or which stabilizes the composition depending on the
purpose of the use. The composition may be used in the form of, for example, a dust, microgranules.
granules, wettable powder or emulsion prepared by a method generally employed in the production of
pesticides.
In the practical application, these various typea of formulation may be used as they are or after
dilution with water into a suitable concentration.
As the agricultural adjuvants herein used, there may be mentioned a carrier (diluent) as well as spreaders, emulsifiers, wetting agents, dispersing agents, binders and disintegrators etc.
As the liquid carriers, there may be mentioned aromatic hydrocarbons such as toluene and xylene, alcohols such as methanol, butanol and glycol, ketones such as acetone, amides such as dimethylformamide, sulfoxides such as dimethylsulfoxide, methylnaphthalene, cyclohexane, animal and vegetable oils, fatty acids and fatty acid esters, etc.
As the solid carriers, there may be mentioned clay, kaolin, talc, diatomacecus earth, silica, calcium carbonate, montmorillonite, bentonite, feldspar, quartz alumina and sawdust.
As the emulsifiers or dispersing agents, surfactants are generally used. They include anionic surfactants, cationic surfactants, nonionic surfactants and amphoteric surfactants such as sodium salts of higher alcohol sulfate, stearyltrimethylammonium chloride, polyoxyethylenealkylphenylethers and laurylbetaine, etc.
These formulations may be used either alone or in t,e form of a mixture with herbicides, insecticides, plant growth regulators, acaricides. germis:des, soil disinfectan+s, soil modifying agents or nematocides. Further, they may be applied to the soil or locus in the form of a mixture with a fertilizer or another agricultural and horticultural disinfectant.
When they are used ir: the above described forms, the concentrations of the compounds used as the effective components in the formulations are varied depending on the forms of the formulations and the agricultural adjuvants used. The concentration is, however, generally in the range of 2-95 wt. %.
The preferred content can be given differently for respective types of formulation. For example, in the case of dust, the content of effective components is 2 te 20%, that of adjuvants being 80 to 98%; in emulsion, the content of effective components is 5 to 40%, that of adjuvants being 60 to 95% in flowable suspension concentrates, the content of effective components is 5 to 40%, that of adjuvants being 60 to 95%, while in wettable powder, the content of effective components is 20 to 80%, that of adjuvants being 20 to 80% and in granules and microgranules, the content of the effective components is 2 to 10%, that of adjuvants being 90 to 93%.
Formulations and methods of putting the invention into effect are given in the following by way of example only.
In the following examples, parts are given by weight

EXPERIMENTAL EXAMPLE 1
Control test for clubroot of Chinese cabbage (caused by Plasmodiphora sp.)
Soil infested with Plasmodiophora brassicae was filled in biscuit pots having a diameter of 15cm.
Then, 10% dust containing the compounds of the present invention as prepared in the same manner as in Formulation Example 1 was added thereto in a predetermined amount and uniformly mixed with the soil. 1 5 Seeds of Chinese cabbage (variety: Taibyo 60-nichi) per pot were sowed. Four weeks thereafter, the seedlings of Chinese cabbage were grubbed out and the conditions thereof were examined.
The test results are shown in Table 1 in terms of a control value which is determined as follows:
Percentage of healthy Percentage of healthy
seedlings in treated plots - seedlings in untreated plots
Control values = - X 100
Percentage of healthy seedlings in treated plots
Number of healthy seedlings Percentage of healthy seedling = X ---- x x 100 Number of total seedlings checked

Control test for damping-off of cucumber (caused by Rhizoctonia sp.)
Field soil was filled in pots having a diameter of 12 cm and then 5 g of infested soil in which
Rhizoctonia solani had been cultured was uniformly inoculated on the soil surface in each pot. The dust of the composition of the present invention prepared in the same manner as in Formulation Example 1 was added thereto in a predetermined amount and uniformly mixed with the soil. Then, 10 seeds of cucumber (variety: Oyashima) were sowed in each pot. They were allowed to grow in a greenhouse.
