Description

一种以氟啶胺为主要成分的杀菌组合物 Fluazinam kind as a main component of fungicidal compositions

技术领域 FIELD

[0001] 本发明涉及一种杀菌组合物,尤其涉及一种以氟啶胺和四氯苯酞为主要成分的杀菌组合物。 [0001] The present invention relates to a fungicidal composition, in particular, it relates to a fluazinam and tetrachlorophthalide as a main component of fungicidal compositions.

背景技术 Background technique

[0002] 稻瘟病是水稻上的三大病害之一,又称稻热病、火烧瘟、叩头瘟。 [0002] Blast is one of the three diseases on rice, also known as rice fever, plague fire, kowtow plague. 中国各稻区均有发生,主要为害叶片、茎杆、穗部。 Chinese rice each have occurred, major damage leaves, stems, spike. 因为害时期、部位不同分为苗瘟、叶瘟、节瘟、穗颈瘟、谷粒瘟。 Because harm period, is divided into different parts seedling blast, leaf blast, Section blast, panicle blast, blast grains. 苗瘟发生于三叶前,由种子带菌所致。 Seedling blast occurred in the first three leaves, caused by contaminated seed. 病苗基部灰黑,上部变褐,卷缩而死,湿度较大时病部产生大量灰黑色霉层,即病原菌分生孢子梗和分生孢子。 Gray base seedling disease, upper browning crimping die, humidity when a large amount of black ash portion disease mold layer, i.e. pathogen conidiophores and conidia. 叶瘟在整个生育期都能发生。 Leaf blast occurred in the whole growth period can be. 分蘖至拔节期为害较重。 Tillering to jointing stage heavy damage. 节温常在抽穗后发生,初在稻节上产生褐色小点,后渐绕节扩展,使病部变黑,易折断。 Thermostat often occurs after heading, early dots on a brown rice section, the expansion section gradually around the black portion disease, easy to break. 发生早的形成枯白穗。 Early blight white head formation occurs. 仅在一侧发生的造成茎杆弯曲。 On one side of the stem causes only bending occurs. 穗颈瘟初形成褐色小点,扩展后使穗颈部变褐,也造成枯白穗。 First panicle blast brown dots are formed, so that the extended neck brown ear, ear also causes dry white. 发病晚的造成秕谷。 Late onset caused blighted valley. 枝梗或穗轴受害造成小穗不实。 Panicle or spikelets cob victims caused untrue. 谷粒瘟产生褐色椭圆形或不规则斑,可使稻谷变黑。 Grain blast a brown oval or irregular spots, black rice can. 有的颖壳无症状,护颖受害变褐,使种子带菌。 Some hull asymptomatic, glume victims brown, the seeds contaminated.

[0003] 稻瘟病病菌以分生孢子和菌丝体在稻草和稻谷上越冬。 [0003] Magnaporthe grisea conidia and mycelia and rice straw in winter. 翌年产生分生孢子借风雨传播到稻株上,萌发侵入寄主向邻近细胞扩展发病,形成中心病株。 The following year conidia spread by wind and rain to the rice plants, germination invade host cells to an adjacent expansion onset, forming a central strain. 病部形成的分生孢子,借风雨传播进行再侵染。 Conidia disease portion is formed, re-infection spread by wind and rain. 播种带菌种子可引起苗瘟。 Contaminated seed sowing can cause seedling blast. 阴雨连绵,日照不足或时晴时雨,或早晚有云雾或结露条件,病情扩展迅速。 Raining, when lack of sunshine or rain and sunshine, or sooner or later there are clouds or condensation conditions, the rapid expansion of the disease.

[0004]目前稻瘟病的防治药剂有多菌灵、三环唑、稻瘟灵等常规药剂,因长期应用已达不到理想的防治效果。 [0004] There are currently Fungicides blast conventional carbendazim, tricyclazole, rice blast and other spirits, because long-term use has reached less than ideal control effect.

[0005] 氟啶胺属2,6_ 二硝基苯胺类化合物,广谱保护性杀菌剂,对链格孢属、葡萄孢属、疫霉属、单轴霉属、核盘菌属和黑星菌属病菌非常有效。 [0005] fluazinam genus 2,6_ dinitroaniline compound, broad spectrum protective fungicide, the genus Alternaria, Botrytis, Phytophthora, Plasmopara viticola genus, Sclerotinia and scab genus of bacteria is very effective.

[0006] 氟唳胺英文通用名:Fluazinam [0006] Li amine fluoro English common name: Fluazinam

[0007] 化学名称:3_氣-N-(3_氣_5_ 二氣甲基_2_批唳基)_ a , a, a-二氣-2,6-二硝基对甲苯胺 [0007] Chemical name: 3_ gas -N- (3_ gas _5_ two gas _2_ batch Li-yl methyl) _ a, a, a- two gas-2,6-dinitro-p-toluidine

[0008]分子式=C13H4Cl2F6N4O4 [0008] Molecular Formula = C13H4Cl2F6N4O4

[0009] 氟啶胺可以防治的具体病害有黄瓜灰霉病、霜霉病、炭疽病、白粉病、番茄晚疫病,苹果黑星病、叶斑病,梨黑斑病、锈病,水稻稻瘟病、纹枯病,燕麦冠锈病,葡萄灰霉病、霜霉病,柑橘疮痂病、灰霉病,马铃薯晚疫病,草坪斑点病等。 [0009] fluazinam preventable diseases are particularly Botrytis, downy mildew, anthracnose, powdery mildew, tomato late blight, apple scab, leaf spot, pear black spot, rust, rice blast , Rhizoctonia solani, oat crown rust, grape gray mold, downy mildew, citrus scab, gray mold, Phytophthora infestans, lawn spot disease. 对抗苯并咪唑类和三环唑的稻瘟病菌也有良好效果,而且氟啶胺耐雨水冲刷,持效期长。 Benzimidazoles against rice blast fungus and tricyclazole have good effect, and rainfastness fluazinam, long duration.

[0010] 但是氟啶胺目前的生产和使用成本均较高,并且长期单独使用也有很大的抗性风险。 [0010] However fluazinam current production and cost are high, and long-term use alone is also a great risk of resistance.

[0011] 将氟啶胺与其它结构的农药有效成分组合进行复配,是解决其单剂应用过程中成本和抗性问题的一种有效的方式。 [0011] The pesticide fluazinam and other structures compounded with an active ingredient combination, is a cost effective way to solve the problem of resistance and its application process in a single dose. 不同结构的农药有效成分混合后,通常表现出三种作用类型,即相加作用、增效作用和拮抗作用。 After mixing the different structures pesticide active ingredient, the type often exhibit three functions, i.e. additivity, synergism and antagonism. 复配增效很好的配方,能提高实际防治效果,降低农药的使用量,还有助于延缓病菌抗药性的产生,是综合防治的重要手段。 Good synergism formula that can actually improve the control effect, reduce the use of pesticides, but also help delay the resistant bacteria is an important means of integrated control. 发明内容 SUMMARY
