Problems solved by technology

Spraying sprout suppressants does not require a lot of space, but uneven application can be a problem
If the medicament cannot be evenly applied to the surface of the potato, it will affect its bud-inhibiting effect
Chemical seed soaking can make potato seed potatoes evenly exposed to the chemical agent, but because the seed soaking requires the use of a thin solution of the chemical agent, the chemical agent must be soluble in water. When soaking the seeds, it is necessary to find the best application concentration and the best soaking time, so it is not easy to master

preparation example Construction

[0058] The present invention also provides a preparation method of the potato bud-suppressing suspension seed coating agent, comprising the steps of: taking uniconazole, a wetting dispersant, a film-forming agent, a thickener, an antifreeze, an additive, a warning color, an antifoaming agent, The preservative and water are mixed and then sanded, sheared and filtered to obtain the product.

[0059] In production, the mass ratio of the potato seed potato to the potato sprout-inhibiting suspension seed coating agent provided by the invention is 1: (100-200).

[0060] The potato sprout suppression composition provided by the invention consists of uniconazole and pendimethalin, and the concentration ratio of pendimethalin to uniconazole is (13-13.5):1. The potato germination inhibiting composition of the invention exerts good medicinal effect on delaying potato germination, can significantly delay potato axillary bud germination, and inhibit potato seed potato germination before pl...

[0062] Example 1: Effects of different ratios of pendimethalin and uniconazole on morphological indicators of potato seed

[0063] In order to confirm the ratio of pendimethalin and uniconazole compound in the seed coating agent, and apply it to practice through the seed coating agent, treat pendimethalin A (A 0 _0mg / L; A 1 _33mg / L; A 2 _165mg / L; A 3 _330mg / L), uniconazole B (B 0 _0mg / L; B 1 _25mg / L; B 2 _75mg / L), configure A 0 B 0 (clean water control), A 2 B 0 (165mg / L pendimethalin), A 0 B 2 (Uniconazole 75mg / L), A 1 B 1 (33mg pendimethalin + uniconazole 25mg) / L, A 2 B 1 (165mg pendimethalin + uniconazole 25mg) / L and A 3 B 1 (330mg pendimethalin + uniconazole 25mg) / L, A 1 B 2 (33mg pendimethalin + uniconazole 75mg) / L, A 2 B 2 (165mg pendimethalin + uniconazole 75mg) / L, A 3 B 2 (330mg pendimethalin + uniconazole 75mg) / L, a total of 9 treatments, 300mL liquid medicine for each treatment, set 3 repetitions, 40 seed potatoes for each repetition, each repea...

[0069] Embodiment 2: Screening of wetting and dispersing agent

[0070]According to the physical and chemical properties of the agents, six wetting and dispersing agents, Tween-80, Nongru 1210#, Nongru 700#, Nongru 1601, Nongru 600#, and Nongru 4103#, were selected for screening tests. Screening of wetting and dispersing agents based on stability, dispersibility, suspension rate, and viscosity. The results are shown in Table 2.

[0071] Table 2 Selection of wetting and dispersing agents

[0072]

[0073]

[0074] The results showed that the suspension rate of the seed coating prepared by six kinds of wetting and dispersing agents were all greater than 90%, and the viscosity of Nongru 1210# was lower, and the thermal storage stability and dispersibility were better.

Abstract

The present invention relates to the technical field of pesticides, particularly to a potato sprouting inhibition composition, a seed coating agent and a preparation method of the seed coating agent. According to the present invention, the potato sprouting inhibition composition comprises uniconazole and pendimethalin, wherein a concentration ratio of the pendimethalin to the uniconazole is (13-13.5):1; the potato sprouting inhibition composition provides good effects on potato sprouting delaying, and can significantly delay potato axillary bud sprouting and inhibit potato seed sprouting before planting; and compared with the uniconazole single agent, the potato sprouting inhibition composition of the present invention has the following characteristics that: the axillary bud is short, the seedling emergence rate after the potato seed planting is not affected, and the seedling emergence effect after the potato seed planting can be improved. The present invention further provides a potato sprouting inhibition seed coating agent containing the potato sprouting inhibition composition, and a preparation method thereof. The potato sprouting inhibition seed coating agent of the present invention has characteristics of long validity period, drug potency centralizing, high utilization rate and safe use. The preparation method of the potato sprouting inhibition seed coating agent has the simple operation and is is suitable for mass production.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a potato sprout suppressing composition, and also to a potato sprout suppressing seed coating agent and a preparation method thereof. Background technique [0002] Potato (scientific name: Solanumtuberosum) is a perennial herbaceous plant belonging to the family Solanaceae, and its tubers are edible. It has become one of the top five crops in the world along with wheat, corn, rice, and sorghum. Potato, as the fourth largest food crop after rice, corn and wheat, has been paid more and more attention by people. In 2015, China will launch the strategy of turning potatoes into a staple food, promoting the processing of potatoes into staple foods such as steamed buns, noodles, and rice noodles. Potatoes will become another staple food besides rice, wheat, and corn. [0003] Potatoes mainly use tubers for vegetative propagation, but the dormant period of potato tubers used as seed ...
