Description

Herbicide composition resistant to rain erosion and its application

technical field

The present application relates to the technical field of herbicides, in particular to a rainwater-resistant herbicide composition and its application.

Background technique

Weeds are one of the three pests in agricultural production. They can compete with crops for growth space, thereby affecting the normal growth of crops, reducing yields, and causing huge losses to agricultural production. In my country, the annual crop yield reduction due to weeds reaches 10 %above. Weeds have the habit of growing wildly. If they are not prevented and controlled in time, they will also affect the appearance of the city and the safety of road traffic.

The current method of controlling weeds is mainly to apply herbicides, which are also called herbicides, which are substances used to eliminate or inhibit the growth of plants. At present, it is widely used to prevent and control harmful plants such as weeds, miscellaneous shrubs, and miscellaneous trees in farmland, orchards, flower nurseries, grasslands and non-cultivated land, railway lines, rivers, reservoirs, warehouses, etc. Since herbicides have the characteristics of good effect, high efficacy, generally low cost and simplicity in controlling weeds, they have made great contributions to the stable, rapid and healthy development of agriculture.

However, the existing herbicides have poor resistance to rain erosion during application, and if they encounter rain within a short period of time after application, the herbicide effect will be affected. Because weeding in non-cultivated land and orchards belongs to the peak period of weeding from June to September, there is a lot of rain at this time. If it rains within 6 hours after spraying, it will often greatly affect the weeding effect and it is difficult to achieve the weeding effect; The control of mature weeds is difficult. The emergence time of weeds is often uneven, so it is difficult to achieve long-term weed control, especially in areas such as non-cultivated land and orchards. Due to management requirements and cost constraints, it is more difficult to control; Narrow, poor weeding effect.

Detailed ways

Definition and Explanation of Terms:

The orchard mentioned in this application refers to the garden where fruit trees are planted, also called orchard, including but not limited to citrus, apple, pear, peach, plum, plum, apricot and other places.

The non-cultivated land mentioned in this application refers to the area where no crops are planted, including but not limited to the front and rear of houses, railways, highways, warehouses, forest fire prevention, ditch sides, roadsides, wasteland, forest land and other lands.

At present, haclopyridine, which is commonly used in wheat fields to control broad-leaved weeds, is ineffective against gramineous weeds. Chloropyridine is currently mainly used in the research, development and application of rice. Stem and leaf treatment can effectively control barnyard grass, broad-leaved weeds and annual sedges, but it has obvious selectivity to weeds. Fluttering grass and perennial sedges including flat stalk grass, firefly rush, water sedge, cow felt, wild water chestnut, etc. are less effective.

Atrazine, a selective systemic pre-emergence and post-emergence herbicide. It is mainly absorbed by roots, with little absorption by stems and leaves, and it is quickly transmitted to plant meristems and leaves, interfering with photosynthesis and killing weeds. Known to be used in corn, sorghum, sugarcane, etc. to control broad-leaved weeds and grass weeds, but the efficacy is seriously affected by drought, rainfall, etc.

Ametryn, a selective systemic herbicide, is a typical photosynthesis inhibitor. Known to control annual weeds in sugarcane, citrus, corn, soybean, potato, pea, carrot fields.

Terbutyzine, mainly absorbed through the roots of plants, is used to control most weeds and is applied before emergence. It is known to be used to control various weeds in crop fields such as corn, wheat, barley, potato, pea, sorghum and citrus, and can also selectively control weeds in citrus, corn and vineyards.

Diuron, a substitute for urea herbicides, has systemic conduction and certain contact effects. The medicament is absorbed by plant roots or leaves and inhibits photosynthesis, resulting in chlorosis of leaves, discoloration of leaf tips and edges, and death of plants due to lack of nutrients. Known to be used in cotton, soybean, tomato, tobacco, strawberry, grape, orchard, rubber plantation and other crops to control annual grass weeds and certain broad-leaved weeds, such as barnyardgrass, crabgrass, foxtail, wild amaranth, Sedge, quinoa, etc.

Among them, atrazine, atrazine, diuron, and terbuthine all belong to photosystem II inhibitors (PSII inhibitors).

Glufosinate-ammonium is a non-conductive contact herbicide. It controls weeds by inhibiting glutamine synthetase, which leads to nitrogen metabolism disorder in plants, nitrogen accumulation poisoning, and then hinders chloroplast synthesis and photosynthesis, eventually leading to plant death. . With years of use, resistant weeds are gradually being reported.

Glyphosate, including its various salts, is an organic phosphine systemic herbicide with a wide herbicidal spectrum. It is found that many common weeds are resistant to glyphosate, and it has been unable to effectively kill the common malignant weeds, resistant weeds, resistant goosegrass and related resistant weeds.
