Description

Rain wash resistant herbicide composition and application thereof

Technical Field

The application relates to the technical field of herbicides, in particular to a rain wash-resistant herbicide composition and application thereof.

Background

The weeds are one of three pests in agricultural production, and can compete with crops for a growth space, so that the normal growth of the crops is influenced, the yield is reduced, great loss is caused to the agricultural production, and the yield reduction of the crops caused by the weeds in China is more than 10%. Weeds have a overgrowing habit, and if the weeds are not prevented and controlled in time, the urban attractiveness and road traffic safety are affected.

The current methods of weed control are primarily the application of herbicides, also known as herbicides, a class of substances used to kill or inhibit the growth of plants. At present, the herbicide is widely used for preventing and treating harmful plants such as weeds, miscellaneous irrigation, miscellaneous trees and the like in farmlands, orchards, flower nursery gardens, grasslands, non-cultivated lands, railway lines, riverways, reservoirs, warehouses and the like. The herbicide has the characteristics of good effect, high efficiency, low cost, simplicity, convenience, feasibility and the like, and contributes greatly to stable, rapid and healthy development of agriculture.

However, the existing herbicide has poor rain erosion resistance in the application process, and if the existing herbicide encounters rain in a short time after application, the weeding effect is affected. Since the weeding in uncultivated areas and orchards belongs to the weeding peak period within 6-9 months, more rainwater exists at the time, and if rainfall occurs within 6 hours after application, the weeding effect is often greatly influenced and is difficult to play a role in weeding; on the other hand, the difficulty of controlling aged and aged weeds is high. The time of emergence of weeds is often uneven, so long-acting weed control is difficult to realize, and particularly in non-cultivated land, orchard and other areas, the difficulty in preventing and killing weeds is greater due to the management requirements and cost limiting factors; in addition, the existing herbicide has narrow weed control spectrum and poor weeding effect.

Detailed Description

Definition and description of terms:

the orchard in the application refers to a garden for planting fruit trees, also called a fruit tree garden, and includes, but is not limited to, fields such as oranges, apples, pear trees, peaches, plums, apricots and the like.

The non-cultivated land in the present application refers to a region where crops are not planted, including but not limited to the front and back of a house, a railway, a highway, a warehouse, forest fire prevention, ditch edge, roadside, wasteland, forest land and the like.

At present, the halauxifen-methyl is commonly used for preventing and killing broadleaf weeds in wheat fields and is ineffective to gramineous weeds. The fluroxypyr-meptyl is mainly researched, developed and applied on rice at present, stem and leaf treatment can effectively prevent and kill barnyard grass, broad-leaved weeds and annual sedge, but has obvious selectivity on weeds, and has poor effects on Euphorbia lathyris, ludwigia prostrata, ribes nigrum and perennial sedge including scirpus planiculmis, iris lactea, cyperus aquatica, boea felterrata and water chestnut and the like.

Atrazine, a herbicide selectively absorbed pre-and post-emergence. The root absorption is the main one, the stem and leaf absorption is little, and the stem and leaf are quickly conducted to plant meristems and leaf parts to interfere photosynthesis and cause the death of weeds. It is known that it is applied to control broadleaf weeds and grassy weeds in corn, sorghum, sugarcane and the like, but the efficacy of it is seriously affected by drought, rainfall and the like.

Ametryn, a selective systemic herbicide, belongs to a typical photosynthesis inhibitor. Are known to be applied in sugarcane, citrus, corn, soybean, potato, pea, carrot fields to control annual weeds.

Terbuthylazine, which is absorbed mainly by the roots of plants, is used for controlling most weeds and is applied before emergence. It is known that it is applied to crop fields such as corn, wheat, barley, potato, pea, sorghum, and citrus to control various weeds, and also to selectively control citrus, corn, and vineyard weeds.

Diuron, which is a substituted urea herbicide, has a systemic conduction effect and a certain contact action. After the medicament is absorbed by the root system or the leaves of the plant, photosynthesis is inhibited, so that the leaves are green, the leaf tips and the edges are faded, and the plants die due to lack of nutrition. It is known to be applied to crops such as cotton, soybean, tomato, tobacco, strawberry, grape, orchards, rubber gardens, etc. to control annual grassy weeds and certain broadleaf weeds such as Echinochloa crusgalli, crab grass, green bristlegrass, wild amaranth, cyperus rotundus, chenopodium quinoa, etc.

Wherein atrazine, ametryn, diuron and terbuthylazine all belong to photosystem II inhibitors (PS II inhibitors).

Glufosinate-ammonium belongs to a non-conductive contact herbicide, and is used for preventing and controlling weeds by inhibiting glutamine synthetase, so that the nitrogen metabolism in plants is disturbed, nitrogen accumulation poisoning is caused, the synthesis and photosynthesis of chloroplasts are hindered, and finally the plants die. With years of use, resistant weeds are also gradually reported.

The glyphosate, including various salts thereof, belongs to an organic phosphine systemic conduction type biocidal herbicide, is a systemic conduction type herbicide, has a broad weed control spectrum, but due to single use for a long time, a plurality of common weeds have been found to generate resistance to the glyphosate in the world, and common malignant weed resistant erigeron breviscapus, resistant eleusine indica and related tolerant weeds cannot be effectively killed.
